A rigid rod resting on a fulcrum has the following 20-lb forces acting on it. A is attached 2 feet from the left of the fulcrum acting vertical upward. B is 4 feet to the left of the fulcrum, acting downward at an angle of 30° with respect to the horizontal. C is 6 feet from the left of the fulcrum, acting upward with an angle of 45° with respect to the horizontal. D is attached 2 feet at the right of the fulcrum, acting downward at an angle of 60° respect to the horizontal. Where can a 20 lb force be placed to put the system in equilibrium?
