Precarious Lunch A uniform steel beam of length I and mass m is attached via a hinge to the side of a building. The beam is supported by a steel cable attached to the end of the beam at an angle 0, as shown. Through the hinge, the wall exerts an unknown force, F, on the beam. A workman of mass m sits eating lunch a distance d from the building. (Figure 1) Figure 1 of 1 +X d 4 m m On L Find T, the tension in the cable. Remember to account for all the forces in the problem. Express your answer in terms of m, m2, L, d, 0, and g, the magnitude of the acceleration due to gravity. T = Submit 15. F = ?
