Engineering Mechanics problem with solution.
Just read the caption and analyze the step by step solution.

The pedestal has a triangular cross section as shown. If it 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. Compute the stress and sketch its distribution acting on the cross section at a location removed from the point of load application.
