Moment [kNm] The moment diagram of an 8-meter beam is given below. The maximum positive moment is 5 kNm at x=3m, where x is the distance measured from the left-end of the beam. The moment equation between x-2m and x-4m is a second order polynomial equation while it is linear elsewhere. Draw the shear diagram and the free-body diagram of the beam.
