3 k/ft A IC В -12 ft- -12 ft- Prob. 10–6

3. Determine the reactions at the supports, then draw the moment diagram. The moment of inertia for each segment is shown in the figure. Assume A and C are rollers and B is a pin. Take E = 200 GPa. 20 kN 20 kN LAB 120(10) mm² [BIBC = 90(106) mm² C |3m|3m|3m| 50 KN 4 m -4 m

Determine the Force in the member AC. AE is constant. D 600 lb 3 ft 400 lb C 3 ft

Determine the vertical and horizontal reactions of each support on the following figures. Assume that the weight of the beam is SN Kilonewton.  FN= 78 SN= 51
