Determine the reactions on the beam. A is a pin support and B is a roller. 30 kN/m A Analyse each force acting on the rigid body and follow the step to solve for the unknowns. -3.6 m 45 kN/m 810 kN m 30 kN/m FB sin 60° N -3.6 m !!! Remember, roller has 1 unknown ONLY, normal to the surface. FB In this problem, the roller is slanted at 60°, therefore it can be resolve in the x- direction and y- direction. BFB cos 60° N Careful when resolving this force. Only 1 unknown must appear FB 60° FBy FB₂ 60° Never resolve it this FB way. This is as if there are two (2) unknowns acting at point B.
