A steel pipe with an outside diameter of 4.31 in.and an inside diameter of 3.90 in. supports the loadings shown. Assume x1 = 17 in., x2 = 8 in., Px

= 4100 lb, Py=1700 lb, Py = 2500 lb, and T = 4200 lb-ft. (a) Determine the normal and shear stresses on,Try on the side of the pipe at point K. (b) Determine the principal stresses (o p1 > o p2)and maximum in-plane shear stress magnitude Tmax at point K, and show the orientation of these stresses in an appropriate sketch.
