Question

A steel bar 5 m x 50 mm is loaded with 250, 000 N. If the modulus of elasticity of the material is 0.2 MN/mm2 and Poisson&#39;s ratio is 0.25, the change in the volume of the bar is :-A-1.125 cm3B-2.125 cm3C-3.125 cm3D-4.125 cm2-C-3.125 cm3

APTITUDE CRACK · Accepted Answer

The correct option is  C 3.125 cm3 @ALL. hERE a steel bar 5m length and 50mm dia...then the original volume will be Pid2/4 multiply length = .01m3. Now change in volume = 25000&Atilde;&middot;( .002 * .2 *10^6) multiply (1 2*.25).01 = 3.125cm3.
