Example 5.1 Determine the support reactions of the propped cantilever beam as shown in Figure 5.2(a).

Solution: The static indeterminacy of the beam is = 3 – 2 = 1. Let reaction at B is R acting in the upward direction as shown in Figure 5.2(b). The condition available is that the .   

(a) Moment area method

The bending moment diagrams divided by EI of the beam are shown due to P and R in Figures 5.2(c) and (d), respectively.
