A 22.4 kg beam is attached to a wall with a hinge and its far end is supported by a cable. The angle between the beam and the cable is 90o. If the beam is inclined at an angle of q = 34.9o with respect to horizontal, what is the horizontal component of the force exerted by the hinge on the beam? (Use the `to the right’ as + for the horizontal direction.) How do I set up this problem?
