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.

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
What difference between top entry and side entry type of ball valve?
Basically a side entry valve would be in two or three parts, and a top entry valve is a compelete housing, the top entry valve would be used where access is difficult to remove and work on the valve, you can work on a top entry while it is on line where as the side entry valve would have to be removed
WHAT IS 24 UNF THREAD PLUG GAUGE?
A thread gauge is a tool used for identifying the particular thread on a bolt or screw. The gauge will have several blades with saw like teeth of different sizes. You match a particular gauge to the thread which will then tell you what size thread it is. gauges come in various pitches to match different screw threads. UNF, UNC, Whitworth, Metric etc. Each has a different pitch angle and thread per inch or millimetre.
An image of a thread gauge can be seen HERE
Will it still work when my radiator fins for CPU cooler are damaged?
That will depend on the degree of the damage to the fins.
If some of the fins are slightly bent there should be no problem at all.
On the other hand if several of the fins are broken off the cooling will probably not be adequate,
Is the microprocessor's internal temperature sensor reporting an unusually high temperature (this is the easiest way to tell if cooling is working right or not)?
What causes propeller shaft drop?
the propeller shaft in the after peak tank is provided with inboard and outboard seals.these seals contain nitrile rubber or viton lip seal which seals against the bronze liner shrunk fit around the cast iron propeller shaft.after a few years it creates grooves on them and naturally looses sealing and sea water can easily find its way inside.this reduces the lubrication effect and creates wear if the bronze liner.now as there is enough clearance the shaft will come down by certain amount because of the propeller weight.this drop in propeller shaft is termed as propeller drop and is measured by POKERS gauge.
What type of valve is used in a peanut butter factory ball or gate or globe or gate?
gate valve. globes are used for throttling and have far too many turns. ball valves are not made for thick stuff. this question was on the inter-provincal exam they had globe valve, gate valve, diaphragm valve and piston valve. for answers too choose from.
What is the minimum thickness of sheathing for attaching cedar shingles on an exterior wall?
19.1 mm is the minimum thickness of sheathing for attaching cedar shingles on an exterior wall.
Using scientific knowledge of forces to build a construction crane is an example of?
The types of scientific knowledge of force that would enable someone to build a crane could include:
- physics
- mechanical engineering
- electrical engineering
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.
That is stress in three dimensions. Biaxial stress is in two dimensions.
Triaxial stress has normal and shear stresses along each of three planes. Most beams can be analyzed with uniaxial stress; plates with biaxial; solids with triaxial
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,...
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 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.
its a solid solution created when carbon steel is heated to red hot. also know as the alpha iron. during cooling of the steel it can transform into pearlite or ferite.
What is a Helical worm gear motor reducer?
For speed reducer gearbox just want to clarify if i can use the worm gear side of the gearbox for the installation of drive motor instead of mounting it on the enveloping worm? what is the advantage and disadvantage
What types of magnetic material are used for small motors?
In very small electric motors which run on dc (direct current) a permanent magnet made of iron - or of some other alloy of elements capable of being magnetised - is used to create the two poles of the stator.
The rotor is built-up using windings made of insulated copper wire wound onto poles made of layers of well-insulated thin cast iron sheets which are called "laminations".
The thin sheets must be well insulated from one another to minimize power wastage caused by internal eddy currents that are induced as the rotor's poles continually break the stator's magnetic field.
In larger motors, which may run on either dc or ac (alternating current), the stator's magnetic field is created by field windings made of insulated copper wire wound around pole pieces which are not permanently magnetized.
For use with ac the stator, like the rotor, must be constructed either:
- using laminations of thin cast iron sheets, well insulated from one another, to minimize power wastage caused by internal eddy currents that are induced into the stator by the field winding, or
- using a non-magnetic material, such as aluminum, which cannot have eddy currents induced into it.
Why does your watch have 21 jewels?
There's a good discussion of jewels in watches here: http://elginwatches.org/help/watch_jewels.html
Manufacturers of cotton canvas hose pipe?
Not exactly sure about this... I know that fire fighters use canvas hoses. Have you tried contacting your local fire department and asking where they buy their hoses? That is where I would start. Also if they can't help you than look up your local plumbing supply house and ask them, they should be able to help you out.
Good luck!
