A mild stell bar 40 mm diameter and 100 mm long is subjected to a tensile force along its axis.(adsbygoogle = window.adsbygoogle || []).push({});

Young's modulus of elasticity = 200 GN m -2. Poisson's ratio is 0.3.

Calculate the force required to reduce the diameter to 39.99 mm

It says use the x-y coordinate system?? This i don't understand?

Thank you
