Problem 1 (40 pts) The massless bar AB has a cable attached to one of its ends and a fixed collar at its other end. The collar has a square hole that fits loosely around a fixed square rod at point A, allowing it to slide without friction. There are two external forces acting on the bar as shown. The 400 N force is parallel to the z axis and the 200 N force if parallel to the y axis. a.) Carefully draw a free body diagram of the bar AB. b.) Determine a unit vector that is in the direction BC. u_BC_x =
