Flying V????

 

Most of us have probably seen large groups of birds flying in formation. These large groups of birds will typically fly in a large "V" shape with one bird in the lead and others trailing behind in two lines.

This formation flight is followed by the birds for two reasons.They are,

First reason :

                   The shape of the formation reduces the drag force that each bird experiences compared to if it were flying alone.

Second Reason :

                      Is that may explain why birds fly in formation is that this orientation allows the birds to communicate more easily. The V formation provides the birds with good visual contact of each other to keep the flock together. This communication minimizes the possibility of losing birds along the way as the formation crosses vast distances during migration.

Results:

Studies have estimated that a flock of 25 birds in formation can fly as much as 70% further than a solo bird using the same amount of energy.

By spacing themselves apart properly, birds can achieve optimum positions that reduce the drag of every bird in the formation. However, not all birds benefit equally.  Apex bird has to work the hardest since it flies into undisturbed air. The upwash(upward thrust) that this bird creates improves the aerodynamics of the two behind it, and these two further improve conditions for the next two birds in line. This means that birds in the middle experience less drag than either the lead bird or the bird at the end of each line.

 

Interesting Point : The birds at the apex and aft positions may interchange their positions after some time so that the flock can migrate to a longer distance.

Degrees of Freedom

Degrees of Freedom(dof)

“No. of parameters needed to specify completely the spatial pose of a rigid body”

A rigid body in ‘d’ dimensions has  d(d+1)/2 no. of degrees of freedom.

d(d+1)/2        =         d          +           d(d-1)/2

           (dof)                 (translations)          (rotations)

• A non-rigid body has infinite no. of dof.

In 3 dimensional space for a rigid body there are 6 dof.

 

• 6 dof:

1.  Moving up and down(heaving)

2.  Moving left and right( swaying)

3.  Moving forward and backward (pitching)

4.  Tilting forward and backward (pitching)

5.  Turning left and right( yawing)

6.  Tilting side to side (rolling)

Dof for a system: A system is defined to be a set of rigid bodies.Its dof can be calculated by

Dof of system = (Dof of bodies) –(internal constraints they may have on relative motion)

Here the dof represents the no. of parameters needed to specify the spatial pose of the system.  

Eg:1

A human arm has 7 dof.

    I.        Shoulder----3----pitch,yaw,& roll

   II.        Elbow--------1----pitch

  III.        Wrist----------3---pitch,yaw,roll 

·         Only 3 of these movements would be necessary to move the hand to any point in space. But people would lack the ability to group things form different angels or directions. 

·         Total no. of dof is 6 

·         A robot/object that has mechanisms to control all 6 physical dof is said to be holonomic 

·         An object with few dof is said to be non-holonomic. 

·         An object with more controllable Dof( than total dof) such as human arm is said to be redundant.

Eg:2

An air plane is a non-holomonic. Since it has only 4 dof

                    I.        Forward motion

                  II.        Rolling

                III.        Pitch (only some extent)

                IV.        Yaw

Eg:3

A car has max. of 15 dof

15 = 6 DOF for the car body+ 1 for each wheel's vertical motion+ 1 for each wheel spinning + 1 for the engine

Eg :4

A human wrist has 27 dof .

• It is the most complicated design that ever made on the earth and it is the system which has the max. no of dof.

•  4 in each finger ( 3 for extension and flexion and one for abduction and adduction)                                     =                                4 x 4

•  the thumb is more complicated and has 5 Dof     = 5

• 6 DOF for the rotation and translation of the wrist =  6

                                                                                           -------------

                                                                                                 27        

                                                                                         -----------              

• Human Hand Not only design but also animating the wrist movements is so difficult such that they animate with only 12 dof neglecting the 15 other dof.

• It clearly unclouded that He is the best designer than any one who born on the earth

Gyro Wheel

Hi

Friends, None of you have learnt the bicycle without facing the wounds. But this generation has the opportunity to enjoy the same but without the wounds. This is possible by only the GYRO Bike which has the self balancing capacity and based upon the  Gyroscopic Principle. 

 For Video assistance click here

Training wheels are a thing of the past thanks to the revolutionary Gyrowheel. Gyrowheel not only keeps the bike from falling over, it also teaches correct riding technique. Gyrowheel senses unbalanced biking and re-centers the bike under the rider’s weight when the bike starts to wobble. Training wheels can’t do that!

Basic Thing

The magic is in the wheel! Okay, it’s not magic inside is a disk that spins independently of Gyro wheel. When the disk is turned on it creates a force the fancy term is “gyroscopic precession” that stabilizes the bike. Gyrowheel provides high stability at very low speed, making learning to ride easier, safer and a whole lot more fun!

WHAT IS PRECESSION AND WHY DOES GYROWHEEL WORK?
Gyrowheel essentially has a gyroscope inside. Gyroscopes are spinning wheels that exhibit a special property called precession. When a force is put at the top of a spinning wheel (such as a rider falling on a bicycle), rather than falling, the gyroscope simply turns, or precesses, in the direction of the fall. This occurs on normal bike wheels when the bike is traveling at higher speeds. Hence, it is easier to ride a bicycle once you "get going." Gyrowheel takes advantage of this property even when the bike is moving slowly. The disk inside Gyrowheel spins independently of the bike wheel. Thus, even when a rider is moving very slowly on the bicycle, the precession of Gyrowheel is still felt. If the rider begins to fall, Gyrowheel precesses under the rider's weight, restabilizing the bike.

Out of the Vortex

Many of us vexed with the conventional turbines which rotates to produce electricity. From my schooling whatever may be the type of generating power there is a rotation of turbine. And I begin to think is there any case to generate power with out the use of turbine and here is the case:

"Fluids passing over objects can set up vortices with potentially disastrous consequences.Technology can capture energy form the turbulent and convert it into clean, cheap electricity"

               When water flows over any structure vortex is created behind the object and it will have a lot of potentiallity. Because of the disruptive power of the vortex induces vibrations named to be vortex induced vibration (VIV), Engineers have long been interested in trying to spoil vortex shedding and suppress VIV to prevent damge to equipment and strucures. And it's amzing that almost no one has tried to tap their power.

Multi Body Dynamics

Multiple interconnected rigid bodies, is termed to be as Multi Body system.And dynamics concerned to the multibody systems is referred to as the "Multi Body Dynamics"

Exergy

According to first law of thermodynamics energy is neither be created nor be destroyed.In the other words it neither appears nor disappears then how can one produce, Save, Conserve the energy. It is clear, but we have to conserve some thing what is it. There comes the term EXERGY.

We have to conserve Exergy but not Energy.

The exergy of a system is the maximum possible work during a process that brings the system into equilibrium. The term Exergy comes into the picture only when there is a potential difference existence between the system and surroundings, but where as energy always exists in the system.

Energy of a system is always constant but where as Exergy always decreases when the system is tending towards the equilibrium.

Energy never talks about the thermal friction but exergy always quantifies the thermal friction and gives a path to the energy engineers to decrease the thermal friction so that the Efficency of the system can be improved.


“The Exergy century has begun. Fight against the thermal friction.”

Course work

Standards set by each country's accreditation society are intended to provide for uniformity in fundamental subject material, promote competence among graduating engineers, and to maintain confidence in the engineering profession as a whole. Engineering programs in the U.S., for instance, are required by ABET to show that their students can "work professionally in both thermal and mechanical systems areas."The specific courses required to graduate, however, may differ from program to program. Universities will often combine multiple subjects into a single class or split a subject into multiple classes, depending on the faculty available and the university's major area(s) of research. Fundamental subjects of mechanical engineering usually include:
• Statics and dynamics
• Strength of materials and solid mechanics
• Instrumentation and measurement
• Thermodynamics, heat transfer, energy conversion, and HVAC
• Fluid mechanics and fluid dynamics
• Mechanism design (including kinematics and dynamics)
• Manufacturing technology or processes
• Hydraulics and pneumatics
• Engineering design
• Mechatronics and control theory
• Drafting, CAD (usually including solid modeling), and CAM

Mechanical engineers are also expected to understand and be able to apply basic concepts from chemistry, chemical engineering, electrical engineering, civil engineering, and physics. Most mechanical engineering programs include several semesters of calculus, as well as advanced mathematical concepts which may include differential equations and partial differential equations, linear and modern algebra, and differential geometry, among others.

In addition to the core mechanical engineering curriculum, many mechanical engineering programs offer more specialized programs and classes, such as robotics, transport and logistics, cryogenics, fuel technology, automotive engineering, biomechanics, vibration, optics and others, if a separate department does not exist for these subjects.

Most mechanical engineering programs also require varying amounts of research or community projects to gain practical problem-solving experience. Mechanical engineering students usually hold one or more internships while studying, though this is not typically mandated by the university.

Mechanical Engineering

is an engineering discipline that involves the application of principles of physics for analysis, design, manufacturing, and maintenance of mechanical systems. Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers design and build engines and power plants, structures and vehicles of all sizes.
It requires a solid understanding of core concepts including mechanics, kinematics, thermodynamics, fluid mechanics and energy. Mechanical engineers use the core principles as well as other knowledge in the field to design and analyze motor vehicles, aircraft, heating and cooling systems, watercraft, manufacturing plants, industrial equipment and machinery, robotics, medical devices and more.

Associations

• SAE (Society of Automotive Engineers)
• ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers)
• ASME (American Society of Mechanical Engineers)
• Pi Tau Sigma (Mechanical Engineering Honor Society)
• ImechE (Institution of Mechanical Engineers) (British)
• Chartered Institution of Building Services Engineers (CIBSE) (British)

Development

Applications of mechanical engineering are found in the records of many ancient and medieval societies throughout the globe. In ancient Greece, the works of Archimedes (287 BC–212 BC) and Heron of Alexandria (10–70 AD) deeply influenced mechanics in the Western tradition. In China, Zhang Heng (78–139 AD) improved a water clock and invented a seismometer, and Ma Jun (200–265 AD) invented a chariot with differential gears. The medieval Chinese horologist and engineer Su Song (1020–1101 AD) incorporated an escapement mechanism into his astronomical clock tower two centuries before any escapement could be found in clocks of medieval Europe, as well as the world's first known endless power-transmitting chain drive.

During the years from 7th to 15th century, the era called islamic golden age, there have been remarkable contributions from muslims in the field of mechanical technology, Al Jaziri, who was one of them wrote his famous "Book of Knowledge of Ingenious Mechanical Devices" in 1206 presented many mechanical designs. He is also considered to be the inventor of such mechaincal devices which now form the very basic of mechanisms, such as crank and cam shafts.

During the early 19th century in England and Scotland, the development of machine tools led mechanical engineering to develop as a separate field within engineering, providing manufacturing machines and the engines to power them. The first British professional society of mechanical engineers was formed in 1847, thirty years after civil engineers formed the first such professional society. In the United States, the American Society of Mechanical Engineers (ASME) was formed in 1880, becoming the third such professional engineering society, after the American Society of Civil Engineers (1852) and the American Institute of Mining Engineers (1871).The first schools in the United States to offer an engineering education were the United States Military Academy in 1817, an institution now known as Norwich University in 1819, and Rensselaer Polytechnic Institute in 1825. Education in mechanical engineering has historically been based on a strong foundation in mathematics and science.

Field of mechanical engineering is normally considered broadest of all engineering desciplines. Work of mechanical engineering can be seen from the bottom of the oceans to the farthest boundaries of space which man has ever been able to reach.

Education

Degrees in mechanical engineering are offered at universities worldwide. In China, India, and North America, mechanical engineering programs typically take four to five years and result in a Bachelor of Science (BSc), Bachelor of Technology (BTech), Bachelor of Engineering (B.Eng), or Bachelor of Applied Science (B.A.Sc.) degree, in or with emphasis in mechanical engineering. In Spain, Portugal and most of South America, where neither BSc nor BTech programs have been adopted, the formal name for the degree is "Mechanical Engineer", and the course work is based on five or six years of training.

In the U.S., most undergraduate mechanical engineering programs are accredited by the Accreditation Board for Engineering and Technology (ABET) to ensure similar course requirements and standards among universities. The ABET web site lists 276 accredited mechanical engineering programs as of June 19, 2006. Mechanical engineering programs in Canada are accredited by the Canadian Engineering Accreditation Board (CEAB), and most other countries offering engineering degrees have similar accreditation societies.

Some mechanical engineers go on to pursue a postgraduate degree such as a Master of Engineering, Master of Science, Master of Engineering Management (MEng.Mgt or MEM), a Doctor of Philosophy in engineering (EngD, PhD) or an engineer's degree. The master's and engineer's degrees may or may not include research. The Doctor of Philosophy includes a significant research component and is often viewed as the entry point to academia.

Mechanical At a Glance

Mechanical Engineering is one of the oldest branches of engineering. Since its beginning it kept on improving its course ware and also fame. In the olden days, Thermal engineering used to be the most important part of mechanical engineering. But today, Mechanical Engineering has shaped itself in various new subjects and forms. For example The Design Engineering, Production Engineering, which are sub forms of Mechanical Engineering are finding their applicability in various forms. In almost all the countries of the world, mechanical Engineering has laid its roots deep into the functioning of the countries. The Mechanical Engineering finds its applicability in almost all the industries today. It is an evergreen branch having constant demand in day to day life.
In the olden days, Mechanical Engineering purely dealt with machinery and production subjects other than Thermal Engineering. But today Mechanical Engineering has found itself with different colors applied to its roots. Though the core part of Engineering remain as usual, some new subjects of this era like Designing and Nano Technology apply colors for the Ever green branch. It is the only Engineering branch which finds its application for ever in all the fields of engineering.

Latest developments....

The latest trends kept on adding new subjects and new versions of old subjects. At present, Design, Analysis and Piping fall under the part of new subjects.

Design has made its entry a decade back into the core part of Mechanical Engineering and got itself manipulated in different forms , for eg Computer Aided Design (CAD) is one of the most familiar Technology these days.

Analysis is the technology used beyond design. Both Design and Analysis are interlinked in actual industry. Analysis is the integral study of an object or a particular compound. In the latest developments, there are a no of softwares available in the market to handle Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) Techniques.

After these advancements, today, there is one more wing from the branch which is "PIPING".

Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid.

Industrial process piping (and accompanying in-line components) can be manufactured from wood, glass, steel, aluminum, plastic, copper, and concrete. The in-line components, known as fittings, valves, and other devices, typically sense and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included in the field of piping design. Piping systems are documented in Piping and Instrumentation Diagrams. If necessary, pipes can be cleaned by the tube cleaning process.

Plumbing is a piping system that most people are familiar with, as it constitutes the form of fluid transportation that is used to provide potable water and fuels to their homes and business. Plumbing pipes also remove waste in the form of sewage, and allow venting of sewage gases to the outdoors. Fire sprinkler systems also use piping, and may transport potable or nonpotable water, or other fire-suppression fluids.

Piping also has many other industrial applications, which are crucial for moving raw and semi-processed fluids for refining into more useful products. Some of the more exotic materials of construction are titanium, chrome-moly and various other steel alloys.

Also, beyond these Computational Fluid Dynamics (CFD) is one more advancement which also has a bright future.Computational fluid dynamics (CFD) is one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the millions of calculations required to simulate the interaction of fluids and gases with the complex surfaces used in engineering. Even with simplified equations and high-speed supercomputers, only approximate solutions can be achieved in many cases. Ongoing research, however, may yield software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial validation of such software is often performed using a wind tunnel with the final validation coming in flight test.

Piping and CFD are the newer advancements which are not yet fully fledged in the industry and they have a very bright future in the next decades.

For fresh graduates...!!

We all should feel proud to be mechanical engineers. A plenty of opportunities are blooming out in the country even in the recession time. But it might be with a great tense of zeel for each and every graduate who comes out successfully by completing the degree. Most of we guys may be without a job in the present thornful condition. Its better to come out without a job rather than to come with a job which would be uncertain!
Right after completing our graduation, there may be different options for us to choose on. Some of us might go with higher education and some for job. There is no much to discuss with the guys who opt for higher education. The mingle starts up with the job seekers! So letz discuss over job hunt now.

For most of us, it will be a very tough question to answer about which job to choose.!

Any how, right after we come out with our graduation, the following are the different fields in which we can find plenty of jobs.

1. Manufacturing/ Production
2. Maintainance jobs
3. Automobile Engineering
4. Design jobs (Integrated with software)
5. Oil & Gas field
6. Field Engineer jobs in Fabrication & Errection
7. Construction & Infrastructure jobs
8. Aeronautical jobs
9. Mining jobs
10. Lecturer jobs
11. Government jobs!
12. Gulf jobs!
13. Jobs abroad!!

1. The Manufacturing & Production sector directly deals with the small scale, medium & Large scale industries where mass production of components will be done. The manufacturing units of all types of components including automobile parts, machinery accessories etc come under this criteria. Jobs in this sector will be hopefully available and pay scale will be average. Once we got into this field, we may have to sacrifice our life for production itself! In case of hard core times these seem to be very delicious!!

2. Maintainance jobs come under the category of Happy Life jobs! These type of jobs will be available in all types of industries including Steel Plants, Power Plants, Manufacturing Units, Cement Plants, Sugar plants etc. But the pay scale for these type of jobs will be comparitively less as compared to others. One can feel the comfortness and freeness in doing a maintainance job! The technical knowledge which we learn for a long 4 years also may not be hopefully utilized in this field! These type of jobs availability will be on average level.

3. The Automobile field is a dream field of most of the engineers. The jobs available in this field will fetch in a need for qualified technical knowledge in the engineer. Its a wonderful sector where only high potential companies will hire engineers. These jobs will be very less in number and also very demanding. To earn such a job, one needs to be technically sound.

4. Design field is the fastest emerging field among all the types of fields in mechanical Engineering. There is a lot of scope for these jobs in the future. Right now, there are a lot of companies which provide design jobs. But there are no big groups which move in the design field. salaries in the design field look pretty awesome!

5. The Oil & Gas field is a very big sector where Major companies work on. All those companies which work on the oil & gas field are country greats. The salaries will be high and there is a great scope for foreign chance. There will also be good weight for the Oil & Gas Engineers!

6.Fabrication & Erection come under plant construction work. All the constructions avail these jobs. These jobs will be similar to oil & gas type. They provide very good salaries & Engineer needs to work in the sight. All the construction companies provide these jobs. Jobs will be available in good number and with high mast companies. These type of jobs will be available on contract basis also.

7.The construction & Infrastructure jobs deal along with civil engineering works. These types of jobs will be available on contract basis. Though many large companies provide these jobs, they are mostly not prefferable as there might not be much scope for future plans. The salaries will be good.

8. Aeronautical jobs are a high category jobs which need powerful technical and personal skills to grab them. They pay a lots of price and not that easily achievable.(But they can be achieved!!)

9. Mining jobs deals directly in the mines which come under the maintainance of mining accessories like conveyors, cranes etc. These are rare jobs and also not that good. But they are some what high payable.

10.I think all the graduates know about Lecturer posts very well. Its upto our own wish, how we rate these type of jobs!!

11. Govt jobs are the gods gifts and there's no much to speak about these!

12.The gulf jobs are highly available in the fields of Oil & Gas, Construction, Fabrication & Errection, Maintainance in cement plants etc. They will be well paying jobs.

13. excluding gulf, Mechanical jobs will be some what better in Europe & USA. In Europe, mostly Automobile jobs will be plenty.

All the above mentioned jobs are available today even in recession.

Software Scope

The design and analysis softwares like AutoCAD, Catia, ProE, IronCAD, CadianMech, Hypermesh etc have washed their way into the market today. As the list has kept on going, it keeps us in perplexity whether which one to cling on with.
In India, most of the high level companies are using AutoCAD as their basic premium software for designing and drafting purpose. Also, proficiently & professionally, AutoCAD deals as the basic concept of design for a design Engineer. Just as C & C++ are for a Software Engineer. Hence the roots of the design are laid from AutoCAD onwards. For every Engineering Graduate, who hopes towards design field must step in through AutoCAD.
After we get perfection in AutoCAD, we ourself can feel like an expertise in Design & Drafting. The further advancements in the design field which are mostly applicable are Catia & ProE. Companies are tending towards these two packages which made work easier than AutoCAD for modeling. So as a professional design Engineer, it is better to choose one among Catia & ProE as a further advancement. Just going on with one of these packages with keeping grip on AutoCAD will make you a perfect Design Engineer.
While peeping on to the edge of the analysis softwares, it is better to step in with Ansys. Ansys is the backbone for all the designing softwares and its the basic one to start on with. Along with this, Hypermesh is a new evolvement which has made surface analysis very easy.
Hypermesh is the deepest point in the surface analysis. It is an excellent tool being very rarely used at present throughout the world. There is a lot of scope for this package as it is an excellent tool which can never be neglected.
A Graduate with all the above specified courses will be a master at Design & Analysis.

Remuneration- Mechanical Jobs

Fluctuations Trend of Remuneration for Mechanical Engineering Jobs

The latest trend of remunerations of mechanical engineering jobs are running high above the sky line. Except for the small scale industry jobs in the manufacturing and production sectors, most other mechanical jobs demand in for high remunerations these days. Though the accelerations of remuneration in these jobs doesn’t grow a lot, the starting pay scales for most of the new Engineers in the fields of E&C(Erection & Commissioning) & O&M(Operations & Maintenance) are flying so high.
The present Software greats of the country like TCS, Infosys & Wipro are paying around 3.2 L per annum for their fresh associates, where as some of the groups like Reliance, Jaypee, L & T, Gammon India, GMR, GVK, Tata Projects etc are paying around 3.6 to 4.2 L for its freshly joined Mechanical Engineers(Technical Jobs). This trend clearly shows the Technical search of talent in the associates.
Hence this trend might be a very good aspect for all the forth coming Mechanical Engineers.
