________________________________________________________________________ PROBLEM (10.123) For the W 610 x 125 shape (see table B.8) beam and loading shown in Fig. P10.118, calculate slope at point D located a/2 from support B. Given: w = 120 kN/m, a = 4 m, E = 200 GPa SOLUTION See solution of Prob.10.118.
