Answer 2

Answer:

An axial pull of 20KN along with a shear force of 15KN is applied to a circular bar of

20mm diameter. The Elastic limit of the bar material is 230MPa and the poission’s ratio is 0.3.

Determine the factor of safety against failure based on:

I. Maximum strain energy stress theory.

II. Maximum Principal strain energy theory
