A pipe with an outside diameter of 8.50 in. and a wall thickness of 0.25 in. is subjected to the loads shown. The internal pressure in the pipe is 320 psi. (a) Determine the normal and shear stresses on the outer surface of the pipe at point K. (b) Show your work to use Mohr's circle to determine the principal stresses and maximum in-plane shear stress at point K. (c) Compute the absolute maximum shear stress at K. 5 ft 1.9 kips 2.75 kips 3 ft 6 ft K H
