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. (Figure 1)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 wb . The professor stands 2.00 meters from the pivot point and has weight wp . Figure1 of 1 The figure shows a beam extending to the right from an end fixed at a vertical surface to a free end. A pulley is placed above the beam. A person stands on the beam below the pulley. A string extends upward and to the left from the right end of the beam to the pulley, then the string goes over the pulley and then it goes vertically downward to the person standing on the beam. Part A Part complete Find the tension T in the rope in terms of the professor's weight wp and the weight of the beam wb . Express your answer in terms of wb and wp .
