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?
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.
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 รท 2 = 2.5 meters.
Therefore, the amount of rope you have pulled through the pulley is 2.5 meters.
10m.(D)
10m yes 2x5m=10m.
Yes, that is correct. The amount of rope you have pulled through the pulley is indeed 10m. Thank you for identifying and confirming the error in my previous response.
To find out how much rope you have pulled through the pulley, we can use the concept of mechanical advantage. Mechanical advantage represents the factor by which the pulley system multiplies the applied force.
In this case, the mechanical advantage is given as 2. This means that for every meter of rope pulled, the load (object being lifted) will be raised by 2 meters.
Since you have lifted the object 5 meters off the ground, it means you have pulled 5 meters of rope through the pulley.
Therefore, you have pulled 5 meters of rope through the pulley.
To find out how much rope you have pulled through the pulley, you need to first determine the relationship between the distance the object is lifted and the amount of rope pulled.
In this scenario, you have arranged a moveable pulley, which contributes to a mechanical advantage of 2. This means that for every meter you pull on the rope, the object will be lifted 2 meters.
Since you have lifted the object 5 meters off the ground, you simply need to multiply that distance by the mechanical advantage of 2 to determine the amount of rope you have pulled through the pulley.
5 meters (distance lifted) x 2 (mechanical advantage) = 10 meters
Therefore, you have pulled 10 meters of rope through the pulley.
