The structure consists of a rigid square and a rod, which at point C are either connected to each other by a hinge or freely rest against each other. The structure is subjected to: a pair of forces with a moment M = 60 kNm, a uniformly distributed load with an intensity of q = 20 kN/m and two forces. Determine the reactions of the connections at points A, B, C. In the final calculations, take a = 0.2 m. Given: K: F₂ = 20 kN; α₂ = 30⁰; E: F₃ = 30 kN; α₃ = 15⁰; CL.
