1. A uniform steel bar with weight of 98 N and length of 3.0 m is suspended on each end by a rope. A 50.0 kg mass hangs 50.0 cm from the left end of the bar. There is a 75.0 kg mass hanging 75.0 cm from the right end of the bar. A person pushes up with a force of 98 N on the center of the bar. How much weight does each rope support? Let S1 be the support force on the left end of the bar.
