1., A beam rests on a fulcrum, 1.2 m from one end. A weight of 350kg is suspended fromthis end causing the beam to balance. If the weight of 350 kg is suspended on the oppositeend of the beam, it is necessary to suspend a 1000 kg weight on the first end in order toeffect an even balance. Find the length of the beam.
