Targ S.M. 1989 C1 variant 23

C1. The rigid frame is situated in a vertical plane is fixed at the point A is pivotally and secured at a point B or a weightless rod hinged at the ends, to the hinge support or on rollers. At point C to the frame tied rope thrown over the block and carrying a weight on the end of P = 25kN. On the frame are a pair of forces with the moment M = 100kNm and the two forces (see. Table). Define the links at the points A and B. When the final calculations take a = 0.5 m.
Given: a point K: F2 = 20 kN; α2 = 60; Point H: F3 = 30KN; α3 = 30.
