Realizing that she often doesn't have her students' full attention during class, a professor devises an elaborate device on which to stand while she lectures. The pulley is placed so that the string makes a 45.0-degree angle with the beam. The beam is uniform, 5.00 meters long, and has weight w_b. The professor stands 2.00 meters from the pivot point and has weight w_p.

Find the tension T in the rope in terms of the professor's weight w_p and the weight of the beam w_b.

Express your answer in terms of w_b and w_p.

Please show me a few steps or all of how to do this problem or give me the answer so I can work backwards. I'm getting stuck on this problem.
