FROM 1. The rigid frame is situated in a vertical plane, the point A is fixed pivotally, and at
The attached or weightless rod with hinges on the ends or the hinge bearing 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: F1 = 10kN; α1 = 75; Point E: F4 = 40kN; α4 = 30.
