A polymer beam was designed to sit on three supports, but the middle support was accidentally placed 0.3 mm lower than the others. Determine the magnitude of the vertical reaction force at B after moment M = 0.68 N·m is applied and causes the beam to rest on all three supports. Let a = 58 mm, b = 58 mm, and EI = 1.05 N·m2. Assume that the supports allow rotation, no deflection at A and C, and no additional deflection at B.
