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 98N on the center of the bar. How much weight does each rope support? (let S1 be the support force on the left end of bar)
Insects do not have lungs as we do, nor do they breathe through their mouths. Instead, they have a system of tiny tubes, called tracheae, find the oxygen concentration at the interior end of the tube
