Avertical bar | is loaded from the bottom with a force of 99767 newtons. if the bar has a diameter of 4 cm, how much does the diameter shrink if young's modulus is 181 x 10^9 pa and the poisson's ratio is 0.38?

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
