Problem 58P
In ?Fig. P5.62? a worker lifts a weight w by pulling down on a rope with a force The upper pulley is attached to the ceiling by a chain, and the lower pulley is attached to the weight by another chain. Draw one or more free-body diagrams to find the tension in each chain and the magnitude of in terms of w, if the weight is lifted at constant speed. Assume that the rope, pulleys, and chains have negligible weights.
Step-by-Step Solution:
Solution 58P Step 1: Let us draw a free body diagram The tension for pulley 1 is will be given by Weights hanging That is W Similarly the only factor acting as tension on pulley two is weight W Hence we have tension as W Therefore T 1 W and T = W 2
Step 2 of 2
