Mechanical Engineering
Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

Normalizing Is a heat treatment process (predominantly used on Steels) It makes the material softer but does not produce the uniform material properties of annealing. A material is normalized by heating it to a specific temperature and then letting the material cool to room temperature outside of the oven. This refines the grain size and improves the uniformity of microstructure and properties of hot rolled steel. Normalizing is used in some in the production of large forgings such as: railroad wheels and axles and on some bar products. The process is less expensive than annealing.
Family friction is when there are problems in a family. The problems in a family could be between everyone or just between two people. But the problem between two people could cause tension in the whole family.
What is a DIY method to calibrate a tripod mounted transit level or check it for accuracy?
To check for accuracy, set up water level, then shoot the ends.
If you mean companies that manufacture welding equipment: * Miller * Lincoln * Thermal Arc * Esab * Arcon * Hobart * Clarke are just a few.
Is MTech beneficial or MBA for mechanical engineer?
M Tech, if you want to continue in your profession (mechanical).
it is a mechanical comparator with magnification in range of 300 to 5000
What are the limitations of a mechanical strain gauge?
these are very costly and cannot meet all the requirements. the values we get from this are also not exact .so,electrical strain come into progress
What is final drive in automobile?
Parts of a vehicle like the driveshaft, differential and axles. Commonly anything after the gearbox going to the wheels.
What is the best building material for Speaker Cabinets?
any wood that would last for a long time and that wont have a rough suface
Metric size #6 shank, 32 is thread pitch per inch. The bigger the no. the bigger the screw size.
metal active gas, doing gas metal arc welding with a gas that isn't inert
What is psycho physiological mechanisms of stress?
psychophysiological - conditions/ stress responses that have both mind and body components
Why is the ability to produce hydroelectric power very great in Latin America?
Latin America has many rivers with a high flow rate hence the great ability to produce hydroelectric power (HEP). In Brazil, a lot of HEP is generated from the Parana river.
Can the same material have high fatigue life but low strength?
Im going to throw in the trick answer: change the shape of the part in question to improve the fatigue and strength properties of the material in question.
Answer 2
Yes. Fatigue requires repeated cycles of loading. If you design a part with low strength but only has a few load cycles throughout the life of the part, then it will never fatigue.
There are several application of Bolts that have low fatigue loading cycles. The screws attaching the interior of your car are low strength and they last forever---because there is very little load cycles applied to it.
Another example: Wooden chair legs never break under fatigue. I wouldn't say that they are high strength part.
Cawas Jehangirji Bardoliwalla - who is he?

How do you build a toothpick structure to hold a 16 pound bowling ball?
Figure out what shape has the strongest structure and only use that shape.
Good thing Mr. Austin is still showing you this and too bad he didn't save my picture.
Why don't nuclear subs use electric motors instead of steam turbines?
nuclear power makes hot water which turns into steam. instead of turbine how about a generator..
Is the hard drive connected to a mounting bracket? If so, what type of screws secure the hard drive to the mounting bracket
Advantages and disadvantages of solid modeling using cad?
It has become common for people to rely on CAD and its analysis tools too much.
Instead of knowing what they are creating they just build and analyse and without understanding the problem the answer might not be right because they dont understand it.
I call these folk CAD monkeys. They get told what to do and they do it without any real knowledge or understanding of what their designing.
CAD is a means (a tool like a hammer) not and end. If I look something common for an example, a car for instance. The car is CAD, the driver is the CAD monkey. Everything works fine until the car breaks down. We then flop around like idiots wait on the AA to fix the car.
The point im trying to make is back in the day before CAD people knew how to do things in their head. But now for the most part were becoming lazy because the knowledge is all freely available we think we dont need to work for it. But we really do.
In the case of the car. We need to be the driver but also be the AA man (or woman if your lucky)
What is the role of electrical engineering drawing for material engineering field?
One of the customers of a material engineer is an electrical engineer. To understand the customer and what he wants, a good material engineer needs to learn the basics of how to communicate with the customer. Engineers communicate through drawings so that means a material engineer needs to learn how to read/create electrical drawings.
When is the pontoon is naturally stable?
When the center of buoyancy is directly above the center of gravity a floating object is stable.
What is the difference between split axle and tandem axle trailers?
Tandem axles are connected by spring Multi axle trailers Shipyard Transporters
