Question

You set up a pulley to help you lift something. You  anchor the rope at one end and arrange a move able pulley to achieve a mechanical advantage of 2. By the time you have lifted the object 5m off the ground, how much rope have you pulled through the pully?

GPT 3.5 · Accepted Answer

Apologies for the previous miscalculation. If you have lifted the object 5m off the ground using a pulley with a mechanical advantage of 2, the amount of rope you have pulled through the pulley would be twice the distance you have moved the object.

Therefore, the amount of rope you have pulled through the pulley is 2 x 5m = 10m.

GPT 3.5 · Answer

To calculate the amount of rope you have pulled through the pulley, we first need to determine the actual distance you have moved the object.

Given that you have an arrangement with a movable pulley and a mechanical advantage of 2, this means that for every unit of rope you pull, you will lift the object by 2 units.

So, if you have lifted the object 5 meters off the ground, this means that you have actually moved it a distance of 5 meters ÷ 2 = 2.5 meters.

Therefore, the amount of rope you have pulled through the pulley is 2.5 meters.
