A uniform horizontal beam with a length of 8.00 m and a weight of 200N is attached to a wall by a pin connection. Its far end is supported by a cable that makes an angle of 53 degrees with the beam. If a 600-N person stands 2.00 m from the wall, find the tension in the cable as well as the magnitude and direction of the force exerted by the wall on the beam. The rotational inertia of the rod about its center is l=1/12mL^2. If the person were no longer standing on the beam calculate the beam's rotational inertia about the hinge.
