since k=E/3(1-2n):
where k=bulk modulus
and n=poision's ratio
it can be seen that value of poision's ratio can't be smaller than 0.5 in order to keep k be +ve.hence poision's ratio is 0.5
What is the poission's ratio in machenical structure ?
is defined as ratio of uniform stress to volume strain
Heat Capacity Ratio "C" is Zero for both Condensor & Evaporator
The speed ratio of the input to the output shaft in a mechanical system, such as a gearbox, is defined as the ratio of the rotational speeds of the two shafts. It is typically expressed as a fraction or a ratio, such as 2:1, indicating that for every two rotations of the input shaft, the output shaft completes one rotation. This ratio is crucial for understanding how torque and speed are converted in mechanical systems. The speed ratio can be calculated by dividing the speed of the input shaft by the speed of the output shaft.
Jet Ratio: it is defined as the ratio of the pitch diameter (D) of the pelton turbine to the diameter of the jet (d). It is denoted by m and is given asm = D/d (=12 for most cases)
between .15 and .20

Poisson's ratio is 0.3 for metals because the metals begin to get thinner the more they are stretched. It also relates a strain that is tensile to a strain that is compressive.Ê
