Problem 4.7 Consider the L-shaped beam illustrated in Fig. 4.55. The beam is welded to the wall at point A, the arm AB extends in the positive z direction, and the arm BC extends in the negative y direction. A force P is applied in the positive x direction at the free-end (point B) of the beam. The lengths of arms AB and BC are a and b, respectively, and the magnitude of the applied force is P. Assuming that the weight of the beam is negligibly small, determine the reactions generated at the fixed end of the beam in terms of a, b, and P. Answers: The nonzero force and moment components are RAX = P(-x), MAy = aP(-y), MA: = bP(-z). %3D
