Problem: The steel pipe has an inner diameter of 2.75 in and an outer diameter of 3 in. The pipe is fixed to the ground at C, and a wrench is attached to the opposite end. The wrench is subjected to a horizontal force of 20 lb that acts in -z direction. Points A and B are located on the surface of the pipe at the same cross section. Note that A lies directly above the -y axis, and B lies directly above the +z axis. 20 lb 10 in. A B X 12 in.. (a) Find the normal and shear stresses at points A and B. (b) Find the principal stresses at points A and B. (c) Show all stresses from parts (a) and (b) on properly oriented elements, relative to the given coordinate system.
