Note: when deriving internal moment equations, use the following orientation of x coordinate: Segment AB: x changes from 0 at support A to a at support B. After making the cut, keep the part of the beam left from the cut. Segment BC: x changes from a at support B to L at point C, where L = a + b. After making the cut, keep the part of the beam right from the cut, i.e. distance from point C to the cut is equal L-x.(a) The Figure la show the cross-section of a beam.
