Question

A metal beam with span L = 3 ft is simply supported at points A and B (Fig. 5-32a). The uniform load on the beam (including its own weight) is q = 160 lb/in. The cross section of the beam is rectangular (Fig. 5-32b) with width b = 1 in. and height h = 4 in. The beam is adequately supported against sideways buckling. Determine the normal stress sigma C and shear stress tau C at point C, which is located 1 in. below the top of the beam and 8 in. from the right-hand support. Show these stresses on a sketch of a stress element at point C.
