The cast iron beam in the figure has an overhang of length b = 2 m at each end. The bending working stresses are 20 MPa in tension and 80 MPa in compression and the allowable shearing stress is 2 MPa. Assume that wo includes the weight of the beam. a. What is the largest allowable intensity wo of a distributed load that can be applied to the beam if P = 5 kN? b. What is the largest P that can be applied to the beam if the intensity wo of a distributed load 5 kN/m?
