Question

4. Calculate the modulus of rigidity and bulk modulus of a cylindrical bar of diameter of 25 mm and of
length 1.6m, if the longitudinal strain in a bar during a tensile test is four times the lateral strain. Find
the change in volume, when the bar is subjected to a hydrostatic pressure of 100 N/mm2
. Take E = 1 X
105 N/mm2
.
