1. The cantilever beam in Figure 1 is fixed at A, and is loaded with a distributed load from A to B and a concentrated moment at C. Use the GRAPHICAL METHOD to plot the shear force and bending moment diagrams for the entire length of the beam. Label values at all key locations on the plots (at changes in loads, maxima, minima, and zeroes). Annotate your diagrams to explain how they were drawn (e.g. “AQAB = (-12 kN/m)(1 m) = -12 kN" and "(dQ/dx)AB =-12 kN/m"). 12 kN/m 5 kNm В D 1 m 0.5 m 0.5 m Figure 1.
