A uniform horizontal beam that weighs 150 N is attached at one end to a wall by a pin connector that allows it to rotate. A cable firmly attached to the wall above the pin supports the opposite end of the beam. The beam is 4.0 m long and the cable is attached to the wall 3.0 m above the pin. a. What is the tension in the cable necessary to keep the beam horizontal in equilibrium? b. What are the horizontal and vertical forces on the pin. 4 g o .
