Determine the slope at D and the displacement at the end A of the beam. EI is constant. Use the moment-area theorems.

Moment Area Theorem. To determine tc/B we apply Theorem 2 by finding the moment of the M/EI diagram between BC about point C. This only involves the shaded area under two of the diagrams in Fig. 7-22b. Thus, 10 tc/x = (1 m)[(2m) (-30 kNm) + () (2m) (0 km) 3 53.33 kN.m
