| Draw an extended free body diagram of the 5.5 m long beam. There is a reaction force, R, at the wall where the beam touches it. To make calculations easy, represent the reaction force, R, with its components, "V" and "H" at the pin hinge. "V" stands for vertical and "H" stands for horizontal. (Measure from the wall.) |
