For the beam and loading shown, write the equations for the internal shear force V and bending moment Mas function of x and then draw the shear and moment diagrams. Also state the values of the internal shear force and bending moment at x = 1.4 m and x = 4.9 m. (Answer: At x = 1.4 m, V = 8.51 kN and M = -23.5 kN m and at x = 4.9 m, V = 2.93 kN and M = -2.77 kN m] Note: The best way to handle this is the integration method. Remember there is a reaction moment at the wall at A. That moment acts like an applied moment and that means there is an initial bending moment which is opposite in sign than the applied moment. In other words, the bending moment shifts immediately upward from 0 at x = 0 if the reaction moment at the wall is CW and downward if is CCW. w 1 w = k1x – k2x2 1.8 kN/m 1 4.1 m -2.9 m
