Most wells do not use pulleys. The traditional style simply winds the rope around the shaft. The mechanical advantage is made by the length of the crank handle, in relation to the diameter of the accumulated rope on the shaft.

How do pulleys make work better?
Well, since a pulley is a SIMPLE machine it makes work better because all you have to do is put effort to a pulley instead of using your hands
Ma of a pulley?
M.a. of a pulley is how much the machine makes work easier
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
What is an example of a fixed pulley?
An example of a fixed pulley would be a well. This is a fixed pulley because the pulley doesn't move even though it is attached to an object.
What is the 2 kind of pulley?
well i know 3, fixed pulley, movable pulley and a pulley system (double pulley with fixed and movable pulleys). i guess its basically just the first 2.
How does a well pulley work?
It works much more effectively, and with greater dedication, focus, and commitment, than an ailing pulley does.
How do pulleys make work better?

How does a pulley decrease work?
No, a pulley redistributes the work making it easier but at the end of the pull it will be the same amount of work.
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.

Diagram of a pulley?
If you google pulley, you'll get a wikipedia article with pictures as well as diagrams.
How does the work you get out of a pulley compare with the work you put into it?
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 is a single moveable pulley?
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
Where can you use a pulley in your daily life?
A pulley can be seen in the Gym. A pulley can be seen on the well - which is used to draw water. A pulley can sometimes be seen on the elevator, which is used to pull the car.
