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 p
oint. 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:
d) 9.55 psi
Explanation:
pressure at the bottom is =ρgh
weight density is ρg=55 lb/ft³
h=25ft
pressure at the bottom is =
=1375psf
1 ft = 12 inch
pressure at bottom =
= 9.55 psi
so, answer will be option (d) which is 9.55 psi
