The young's modulus of a wire of length 2m and area of cross section `1mm^2` is `2 xx 10^10 N/m^2`. What is the work done in increasing it's length by 2mm.

For silver, young's modulus is 7.25 xx 10^10 N/m^2 and bulk modulus is 11 xx 10^10 n/m^2 . What is the poisson's ratio ?

A 5 kg wt is suspended from the end of a wire 2.5 m long fixed to a rigid support. The diameter of the wire is 2 mm. If Y = 20 x 10^10 N/m^2 for the material of the wire, find the increase in its length.g = 9.8 m/s^2 .

A force of 100 N produces a change of 0.01% in a length of wire of area of cross -section 1.0 mm^2 . Young's modulus of the wire is

The bulk modulus of a liquid is 2 xx 10^10 N/m^2 . What is the percentage decrease in the volume of the liquid , when the pressure is increased by 20 atmosphere > ( one atmosphere = 10^5 N /m^2 ).
