Targ S.M. 1989 C2 option 02

The structure consists of a rigid angle piece and a rod, which at point C or are connected to each other, are hinged or freely resting on each other. The design is affected by: a pair of forces with a moment M = 60 kNm, a uniformly distributed load with an intensity q = 20 kN / m and two forces. Determine the reaction of bonds at points A, B, C. For final calculations, take a = 0.2m6
Given: L: F₁= 10kN; α₁= 15⁰; E: F₃ = 30kN; α₃ = 60⁰; AE.
