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.

Where is the fuel pump on your 1986 ford e350?

My '82 has a mechanical pump toward the front of the lower part of the engine on the driver's side. If yours isn't there it's an electric pump, probably inside the gas tank.

How do you calculate degree of freedom for a robotic arm?

The degree of freedom (DOF) of a robotic arm can be computed based on the number of the joints and types of the joints. For most robotic arm, the joint is either prismatic or revolute(about one axis), the DOF is simply the total number of the joints.

What is Scope of doing mtech in computer integrated manufacturing?

Computer-Integrated Manufacturing (CIM) in engineering is a method of manufacturing in which the entire production process is controlled by computer. The traditional separated process methods are joined through a computer by CIM. This integration allows that the processes exchange information with each other and they are able to initiate actions. Through this, integration the manufacturing can be faster and with fewer errors, although the main advantage is the ability to create automated manufacturing processes. Typically CIM relies on closed-loop control processes, based on real-time input from sensors. It is also known as flexible design and manufacturing. It includes CAD/CAM, computer-aided design/computer-aided manufacturing, CAPP, computer-aided process planning, CNC, computer numerical control machine tools, DNC, direct numerical control machine tools, FMS, flexible machining systems, ASRS, automated storage and retrieval systems, AGV, automated guided vehicles, use of robotics and automated conveyance, computerized scheduling and production control, and a business system integrated by a common data base. Therefore the scope for such complicated technology in today's time is tremendous. Hope this helps. All the best!

Define thermal stress and thermal strain?

Thermal stress ( and strain) arrises at situations, when there are some area with diffrent temperature in the same body. Or at situatiom - one konstruction part restricts thermal expansion ( dilatation ) another part. Or - two parts (f.e. austenit - ferrit steels ) are in welded connection.

What is normalising process?

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.

What is family friction?

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.

Names of welding companies?

If you mean companies that manufacture welding equipment: * Miller * Lincoln * Thermal Arc * Esab * Arcon * Hobart * Clarke are just a few.

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

What is 6-32 screw?

Metric size #6 shank, 32 is thread pitch per inch. The bigger the no. the bigger the screw size.

How does MAG weld mean?

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.

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..
