QN:3 Suppose that your professor decides to lecture while sitting on a 20 kg beam of length L. Apply the conditions of equilibrium separately to the professor and to the beam. Use the equations to determine the force of the cable on the beam and the force that the professor exerts on the beam. The gravitational force that the Earth exerts on the professor is 600 N.

In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
