a uniform beam of weight 420 N and length 3.2 m is suspended horizontally. On the left it is hinged to a wall; on the right is it supported by a cable bolted to the wall at distance D above the beam. The least tension that will snap the cable is 1200 N.
(a) What value of D corresponds to that tension?
(b) Give any value for D that won't snap the cable.
John, we are not going to work homework or test questions. We will, however critique your work or thinking.
