Lou is promoting the grand opening of Roswell’s, a new nightclub with an alien theme. One end of a uniform 100-kg beam, 10 m long, is hinged to a wall, and the other end sticks out horizontally over the dance floor. A cable connects to the beam 6 m from the wall, as in Figure. Lou sits at the controls of a mock UFO, which hangs from the free end of the beam. From there, he sends down abduction beams, hypnotic light effects, and spaceship noises to the patrons below. If the combined weight of Lou and his UFO is 400 kg,

(a) What is the tension in the cable?

(b) What is the horizontal force on the hinge?

(c) What is the vertical force of the beam on the hinge?
