A uniform horizontal beam 10 m long is attached by a frictionless pivot to a wall. A cable making an angle of 30o (to the beam) is attached to the beam 6 m from the pivot point, supports the beam, which has a mass of 100 kg. The breaking point of the cable is 4000 N. A man of mass 100 kg walks out along the beam. How far can he walk before the cable breaks?
