A cantilever hydraulic crane is required to lift a load of 60 KN as shown in figure. The single rope supporting the load passes over two pulleys and then vertically down the axis of the crane to the hydraulic apparatus. The section of the crane at CD is also shown. Apply theory of combined stresses for straight beams to determine the maximum compressive and tensile stresses in the section
