Two 25.0-N weights are suspended at opposite ends of a rope that passes over a light, frictionless pulley. The pulley is attached to a chain from the ceiling. (a) What is the tension in the rope? (b) What is the tension in the chain?

Solution 1E Let us have a look at the free body diagram as shown below. From the free body diagram as shown above, T + T = 25.0 + 25.0 2T = 50.0 T = 25.0 N (a) Therefore, the tension in the rope is 25.0 N. (b) Let the tension in the chain be T .cThis tension will be balanced by the sum of the two weights. Therefore, T c = 25.0 N + 25.0 N T c= 50.0 N Therefore, the tension in the chain is 50.0 N.
