The simply supported beam consists of a W410 × 85 structural steel wide-flange shape [E = 200 GPa; 1 = 316 x 106 mm4]. For the loading shown, use discontinuity functions to compute: (a) the slope of the beam at A, and A (b) the deflection Vmid of the beam at midspan. Assume LAB LCD = 2.7 m, LBC = 3.9 m, w = 75 kN/m.

Follow-up Question

When I put it in the answer was incorrect. When calculating Ra shouldn't it be Ra = -2.7(75)-2.7(75) because there are two w's. Also why does the FBD look like that?
