The WORK is the same. Work = force times distance. If the pulley allows you to pull half as hard, you will have to pull over twice the distance (length of rope), making the same total work.
(Ignoring friction; you would actually have to do slightly more work to overcome the friction in the pulley.)

What do you put on a screaming pulley bearing?
Put on a new pulley bearing.
How can a fixed pulley and movable pulley be put together?
With the string from the movable pulley
What is the formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
Where to put the fan pulley holding wrench?
On the fan pulley...
How do you replace the idler pulley in a 95 Dodge Stratus?
Remove belt. Remove the bolt and then pull the pulley off. Put new pulley in position. Put the belt back on.
What is the function of pulley?
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.
How do you change the idler pulley on a 1994 explorer?
On the belt routing diagram under the hood (near the grille, but under the hood) you will find the location of the 'tensioner' pulley. You need to get a 15mm socket and place it on the bolt on the tensioner pulley. Then use a ratchet to put clockwise pressure on the bolt to loosen the tension on the belt. This will allow you to remove the belt from the idler pulley, remove the bolt, put on the new pulley. Now put clockwise pressure on the tensioner pulley again to put slack in the belt so you can slip it around the new idler pulley. You're done.

How do you change the idler pulley on a 43 vortec?
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on
How do you change alternator belt on a 1998 Nissan maxima?
loosen the tension pulley bolt which is in the middle of the pulley, use a wrench, little work space is provided, just a little bit, then lossen the bolt that is behind the pulley, tho relive tension in the belt. take off the belt, and put on new one and tighten the bolt behind the pulley till belt is tight, then retighten the pulley bolt.
A person does 50j of work to lift a crate using a pulley. the pulley's work output is 42j. What is the pully's mechanical efficiency?
The mechanical efficiency of the pulley is calculated as: (Work output / Work input) * 100%. In this case, it would be (42J / 50J) * 100% = 84%. The pulley is 84% efficient at converting input work into output work.
How do you install an alternator belt on a 95 Grand Am?
Loosen the tensioner pulley. Put the belt around the alternator pulley and the tensioner pulley. Move the tensioner pulley to the right until the belt is tight. Tighten the tensioner pulley.
