Mechanical Engineering

At the time of turning long bars the follow rest and steady rest are used.

Follow rest is used near to the tool at the back side of the job ie bar and it moves along with the tool such that it gives support to the job so that the job does not get deflected due to the tool preacher.

Steady rest is used to give support to the job in the middle or at a end so that the job should not get bend.

When Turbine shaft temp is below 100 deg.centigrade,Then rolling of turbine carried out it is called cold rolling.

In Volute Casing, area of flow increases gradually, Due to this, the amount of movement of water opposite to the general flow of water is more. This movement of water against the actual flow of water is called EDDIES in Volutes casing of Centrifugal pump.Where as in Vortex casing area of flow is uniform and effect of formation of eddies is very less.

Because of their tendency to stick to the blade.

the function of air vessel is to accumulate excess quantitiy of water flowing in the suction pipe or delivering pipe compressing the air inside the vessel

Double slider crank mechanism is used where two slider works or the crank also work as a slider it uses to transform Reciprocating motion into rotary

in general entropy will not decrease in a spontaneous process since spontaneous process are all irreversible ones. entropy can be reversed only through an reversible process by an ideal engine but it is impossible to create such an engine by violating second law of thermodynamics. hence entropy cannot be decreased practically

Ultimate Tensile Strength is the (BHN*500)

Gives an indication of the relationship between fine material and coarse material in a gravel mix. The higher the GM the more coarse material.

Both are Same, Applied Mechanics is commonly referred to as engineering mechanics

It is the direction in line with (parallel to) the axis of the part. If you have a cylindrical shaft, for example, the axial direction runs along the length thru the center of the circular ends.

Any pipe having pressure greater than 3.5kg/cm2 or having a size more than 254cm & is connected to steam generating circuit is known as IBR pipe & the rest are non-IBR pipe

becoz loaded truck has got more weight than the empty truck.....so becoz of which loaded truck has got more friction in tyres compared to empty truck...this may the reason why loaded truck starts slow than the empty truck

Most material being welded to 2205 including itself, should be welded with 2209 filler wire.

pirani guage can measure upto 10^-3 torr pressure

but

penning guage can measure beyond this

The principle stress is a maximum tension stress in a body where shear stress is zero and it acts on the principle plane. If a body is under both tension and shear then the principle stress is higher than the initial tension stress. You can calculate this and find the principle plane angle using Mohr Circle analysis or equations.

Heating a metal decreases the tensile strength and increases ductility

A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
