If the pedestal is subjected to a compressive force of 500 lb, specify the x and y coordinates for the location of point P(x, y), where the load must be applied on the cross section, so that the average normal stress is uniform. Calculate the stress and sketch its distribution acting on the cross section at a location removed from the point of load application.
