Calculate BM: M = Fr (Perpendicular to the force) In equilibrium, so ΣMA = 0 But to find the Bending Moment, you must cut the beam in two. Bending moment is INTERNAL, moment is EXTERNAL. A good way to double-check is to do moments for BOTH sides and compare. In engineering, we are concerned with the MAXIMUM BM.
