50 kN/m 7.66 For the beam and loading shown, (a) Use discontinuity functions to write the VI expression for w(x). Include the beam reactions in 20 kN/m this expression. (b) Integrate w(x) twice to determine V(x) and Mx). (c) Use V(x) and M(x) to plot the shear-force and bending-moment diagrams. B 3 m 1 m Fig. P7.66
