Pulleys are used for two quite different operations.
The simplest are used to transfer power from one place to another in association with chains or belts. Examples would be a a simple saw bench where pulleys are on the motor spindle, and another on the saw shaft. Or the pulleys at the front of your car engine which drive the water pump. and maybe the fan as well.
In a another simple mode, they are used to change the direction of a force, such as are used for drawing water up from a well.
Compound pulleys are used to obtain some mechanical advantage, such as in hoisting a sail, where the rope passes through several sets of pulleys. This substitutes a smaller force over a longer distance, for a great force over a short distance.
In a simple pulley system, the ends of the rope (belt, chain) are attached to the load and to the driver.
In a compound pulley system, one (or both) of the pulleys are themselves fixed to the load or the ground, and the rope has only one free end, the other being attached to the second pulley.
What else can I help you with?
Give an example of a pulley?
A common example of a pulley is a flagpole pulley system, where a rope is used to raise and lower a flag. The pulley helps to reduce the amount of force required to lift the flag by distributing the load.
What is an example of a fixed pulley?
An example of a fixed pulley is a flagpole. The pulley is attached to the top of the pole, and the rope passes through it to help raise and lower the flag. The pulley remains stationary as the flag is moved up and down by pulling on the rope.
What is an example of a pulley in the bedroom?
An example of a pulley in the bedroom could be a ceiling fan. The mechanism that controls the speed and direction of the fan is typically operated using a pulley system.
What is an example of a movable pulley?
An example of a movable pulley is a flagpole. When you pull down on one end of the rope, the pulley at the top of the flagpole moves with the flag, making it easier to raise and lower the flag.
What is the example of pulley?
An example of a pulley is a clothesline pulley system used to hang and dry clothes. The pulley helps to lift the clothes up and down easily, making it more convenient to hang and retrieve the clothes.
What are some example sentences for 'pulley'?

What does a fixed pulley consist of?
A fixed pulley is a wheel and axle attached to an anchor point that does not move. An example of this is in a single pulley system where the rope goes up to a hanging pulley, over the wheel of the pulley and back down to the ground again.
