4-32. For the structure shown, draw free-body diagrams for both the beam ABC and the link BD. The members are weight- 4-34. For the pin-connected frame shown, sketch a free-body diagram of (a) the entire frame, (b) the member AC, and (c) the member DF. Neglect the weight of the members. less. F. 45° Cable Problem 4-32 A D 4-33. A 1200 Ib load is supported by a cable that runs over a small pulley at E and is anchored to a bar DA, as shown. Sketch free-body diagrams of bars EB and DA and of the pulley. The bars are pin connected at each end. Neglect the weights of the mem- bers and the pulley. Problem 4-34 4-5. A weight Wis supported by a flexible cable and an inclined bar, as shown. The bar is pin connected at a vertical wall. Sketch the free-body diagram for the bar.
