You set up a pulley to help you lift something. You anchor the rope at one end and arrange a moveable 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 pulley? 10m because 2x5= 10?

Question

You set up a pulley to help you lift something. You anchor the rope at one end and arrange a moveable 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 pulley?  10m   because 2x5= 10?

GPT 3.5 · Answer

Yes, you are correct. Since you have arranged a movable pulley with a mechanical advantage of 2, for every 1 meter you pull, the object will be lifted by 2 meters. Therefore, to lift the object 5 meters, you need to pull the rope through the pulley for a total distance of 10 meters (5 meters lifted x 2).
