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.

What is the function of the camshaft pulley?
It makes things easier by putting rope through on end and pulling a weight up with little effort
What is a column cap plate and what is its purpose?
column cap plates are commonly used to secure the column head to a beam using bolts driven through the plate and beam bottom flange. The plate is welded to the column head usually with fillet welds although fully penetrating butt welds would be better since this would provide the greatest restraint to bending and shear (transverse/longitudinal) at the plate/column head junction.
A person who works on both clocks and watches or watches alone (for some reason) is called a Horologist. But I have been told by a French man who has four generations of watch/clockmakers in his family that a clockmaker that only works on clocks is called a Pendulier (can't find the correct spelling)
Why flywheel is used in reciprocating compressor not in centrifugal compressor?
Flywheel prevents fluctuation in the speed of the motor as a result of load fluctuation. It stores the energy and dissipates it to the compressor for prolonged period. So the load fluctuation which is high during compression stage and low during other stages during a cycle in reciprocating compressor gets nullified. On the other hand, centrifugal compressor continiously compresses the gas and does not have load fluctuations, hence flywheel is not required.
What is difference between nace pipe and pipe?
CS Normal pipe will be meeting the Specification (ASTM/ASME) standard requirements. NACE Pipes will be having additional restriction in Chemical Composition,Hardness,Carbon Equivalent and Heat treatment requirements.This additional requirements to ensure the usability of
material in Sour services.
What is the function of a column in a drill press?
The table slides up and down to accomodate the material you are drilling.
Why goose neck is used in boilers?
goose neck have following two functions:
1. It increase the speed of flue gas in convective zone of the boiler, as velocity increase heat transfer rate also increases which is necessary for super heaters.
2. It divert the path of flue gas and spread it in all corners of the boiler,...
You aren't letting the gas settle. You're letting the oil settle. Running the freezer before the oil settles will have the same effect as running your car with no oil. i.e. Overheating and the possibility it could sieze
Type your answer here... CAF gasket refers to Compressed asbestos fibre gasket. This gasket is carcinogenic and hence industries have started to reduce this material.
How do you reset samsonite tsa 005 lock?
With cable inserted, lock code on current code or factory code 000, if you haven't changed it, turn the lock up diane down. The button on the bottom is oval. Put your fingernails on both ends, and life the button away from the lock housing, and turn it 90 degrees. Set your new code. Return the button housing back to its original position. Push button in all the way to release the cable. Should be all ready to go.
How do you identify upstream end of a ball valve?
in open condition the valve handle lever indicates the upstream end of a ball valve
ANS 2 - Most ball valves where that matters will have an arrow embossed on the valve body. In the case of many ball valve flow direction is immaterial.
What is deposition in thermodynamics?
Deposition is the direct solidification of a vapor by cooling; the reverse of sublimation.
Describe how to work harden a metal?
Cut a straight piece of metal coat hanger, about 10 inches long. Bend it back and forth a few times. The point where the bend is will now be work hardened.
*If you repeat this bending too many times, it will break because the hardening also makes it brittle.
What are face plates used for on the lathe machines?
On a wood turning lathe, the faceplate is screwed to the piece of wood, then the faceplate is held in place by the chuck. This facilitates free-wheeling the opposite end for such items as bowls.
Almost similar to a wood turning lathe, the face plate on a metal lathe is a device that is used instead of a chuck. It allows a workpiece to be clamped or bolted to it for machining.
It is a stop valve placed on an auxiliary piece of equipment. Or it could be placed at the steam main to feed an auxiliary steam system (heating, auxiliary pumping. etc.). It is not the Main steam stop for the boiler or the prime mover (engine, turbine, process), it is for a secondary service.
Backstep welding is a technique to avoid distortion while welding on thin sheets. In the backstep technique, the general progression of welding may be left to right, but each bead segment is deposited from right to left. As each bead segment is placed, the heated edges expand, which temporarily separates the plates at B. As the heat moves out across the plate to C, expansion along outer edges CD brings the plates back together. This separation is most pronounced as the first bead. With successive beads, the plates expand less and less because of the restraint from the prior welds.
Many ways are used to communicate technical information, such as, oral and written
In all cases enough detail must be included to fully understand without confusion.
Gross Domestic Product is calculated by summing up?
Gross domestic product or GDP generally is defined as the market value of the goods and services produced by a country and is calculated per quarter. One method of calculating is summing up all expenditures in the country and is known as the expenditure approach.
What is the definition of scour pipe?
A scour pipe is used to flush out sediment or release water. It usually runs near the bottom of a dam.
