A pipe with an outside diameter of 140 mm and a wall thickness of 7 mm is subjected to the 16-kN load shown in Figure P15.79. The internal pressure in the pipe is 2.50 MPa, and the yield strength of the steel is

_Y
= 240 MPa. Determine

(a) the factors of safety at points H and K predicted by the maximum-shear-stress theory of failure.

(b) the Mises equivalent stresses at points H and K.

(c) the factors of safety at points H and K predicted by the maximum-distortion-energy theory.
