(see figure) supports a uniform loadof intensity q 240 lb/in., which includes the weight of the beam. Calculate the shear stresses in the beam (at the cross section ofmaximum shear force) at points located 1/4 in., 1/2 in., 3/4 in., and 1 in.from the top surface of the beam. From these calculations, plot a graph
