Problem 3.9 Consider the L-shaped beam illustrated in Fig. 3.37. The beam is mounted to the wall at point A, the arm AB extends in the z direction, and the arm BC extends in the x direction. A force F is applied in the z direction at the free-end of the beam. (a) If the lengths of ams AB and BC are a and b,respectively, and the magnitude of the applied force is F, observe that the position vector of point C relative to point A can be written as r= bi+ ak and the force vector can be expressed as F = Fk, where ij, and k are unit vectors indicating positive x, y, and z directions, respectively.
