Question

1. Buckets and a Pulley Two buckets of sand hang from opposite ends of a rope that passes over an ideal pulley. One bucket is full and weighs 120N ; the other bucket is only partly filled and weighs 60N .

PART A:Initially, you hold onto the lighter bucket to keep it from moving. What is the tension in the rope? In N.

Part B:You release the lighter bucket and the heavier one descends. What is the tension in the rope now? In N.

Part C: Eventually the heavier bucket lands and the two buckets come to rest. What is the tension in the rope now? In N.

Explanation / Answer

PART A: When you hold on to the lighter bucket, the only force pulling the rope is by heavier bucket.

So tension in rope= 120N

PART B: The resultant tension now becomes the difference between weights on both sides

So tension= 120N-60N= 60N

PART C: Since the heavier bucket landed, the only force pulling the robe is by lighter bucket.

So tension= 60N
