Solve the problem.For a simply supported beam with a load that increases uniformly from left to right, the bending moment M (in ft?lb) at a distance of x (in ft) from the left end is given by M = 
(wl2x - wx3). Determine the location of the maximum bending moment. In the formula, w is the rate of load increase (in 
) and l is the length (in ft) of the beam.
