- Q: A crane lifts a 1265 kg steel beam vertically 26 m, it then stops and swings the beam 3 m horizontally into a position where the welders can secure it into its proper position. What is the work done on the beam by the crane? What is the work done by the force of gravity on the beam?
- the work done on the beam by the crane = 1265 * 9.81 * 26 + 1265 * 9.81 * 0 = 322651 J answer work done by the force of gravity on the beam = 1265 * 9.81 * 26 + 1265 * 9.81 * 0 = 322651 J answer
