I need help solving Problem 5.30

5.29) Knowing that P = Q = 480 N, determine (a) the distance a for which the absolute value of the bending moment in the beam is as small as possible, (b) the corresponding maximum normal stress due to bending. (See hint of Prob. 5.27.

5.30) Solve Prob. 5.29, assuming that P = 480 N and Q = 320 N.
