Need Help with Part e only. What is the magnitude in newtons of the tension in the cable

(9%) Problem 4: Abeam, uniform in mass, M = 40.1 kg and length L = 28.7 In, hangs by a cable A _ 0 + supported at point B , and rotates without friction around point A. On the end far of the beam, an object of ssume W ' mass m = 6.8 kg is hanging. The beam is making an angle of 0 = 38.9 at pointA with respect to the + x- B axis. The cable makes an angle q) = 24.6 with respect to the - x-axis at B. Assume 1]) = 0 + 4). 7 14% Part (a) Select the correct free body diagram. In the gure the tension is T, horizontal and vertical components of the support force are S x and Sy, F 3 is the weight of the beam, and F m is the weight of the mass. I/ Correct! 7 14% Part (b) Enter an expression for the lever arm for the weight of the beam, [3, about the point A. [B = ( L/2 ) cos(6) V Correct! 7 14% Part (c) Find an expression for the lever arm for the weight of the mass, 1\
