Homework (2D equilibrium - sample) G a B Two beams of lengths 4a (horizontal) and 2a (a = /4), both of distributed linear unit weight q [N/m], are connected at B by a cylindrical bearing (joint) as shown. At the distance a from B, a load of weight G [N] is applied. Derive equations of equilibrium, necessary to determine reactions at the fixed support A, and the reaction at the frictionless support C.
