Question

In figure, draw a tackle to lift the load by applying the force in the downward direction. State how many strands of tackle are supporting the load.

Open in App

Solution

In general, if the total number of pulleys used in both the blocks is n and the effort is applied in the downward direction, then the ension in the n segments of the string support the load.
Here $n = 5$ , so 5 strands of tackle are supporting the load.
