A bolt is tightened, subjecting its shank to a tensile stress of 80 kpsi and a torsional shear stress of 50 kpsi at a critical point. All of the other stresses are zero. The material is a brittle material

A bolt is tightened, subjecting its shank to a tensile stress of 80 kpsi and a torsional shear stress of 50 kpsi at a critical point. All of the other stresses are zero. The material is a brittle material with Sut =80 kpsi and Suc =150 kpsi. Find the factor of safety at the critical point by the more conservative failure theory and determine if the bolt will fracture.

Answer:

factor of safety is 0.77

fracture of bolt will occur since principle stress exceeding бmax on the bolt.
