Question

A bolt is to a tensile load of $25\text{kN}$ and a shear load of $10\text{kN}$. Determine the diameter of the bolt according to

(a) Maximum principal stress theory

(b) maximum shear stress theory

Assume factor of safety as $2.5$, yield point stress in simple tension = $300\text{N/mm}^2$.
