Both pulleys and levers are mechanical devices designed to gain an advantage over an inert load force and both are simple machines. The main difference with a pulley system is the direction of force, and the effect can be different.

How do you find the mechanical advantage of a simple machine?
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
How is a lever different from a pulley used with ropes?
A lever and a pulley are different. They are both simple machines that have been around for over two thousand years and described in detail by a Greek named Archimedes.
How did pulleys build pyramids?
They used ropes and other materials in Egypt to put it together.
What is a simple machine made from a wheel and rope?
A simple machine made from wheels and ropes is a pulley.
How does a lift bridge work?
There are 2 towers. The segment in the middle is on a rail on the towers. Ropes goes from the ends of the middle segment up to a pulleys on the towers and from there to motors at the ends of the bridge. When the motors run the pull the middle segment up.
What kind of a simple machine is a rope?

How are laces like pulleys?
Because they are like ropes
What is the meaning of the word pulleys?
Pulleys are like a lever system. They involve using ropes or chords strung through something up higher, and by using body weight or the momentum of another object, you can lift an item that you couldn't have with just your grip and arm strength.
What kind of simple machine is a paint can opener?
A paintbrush is not a machine in the sense that the word "machine" is used in elementary physics. Machines are used to do work, usually by providing leverage in some way. In that way, Atwood's machine, a collection of ropes and pulleys, is a machine, but the gasoline engine is not. This is merely an issue of terminology and classification and has historical roots. It is not a statement of a basic law of science.

How does the number of supporting ropes on a pulley affect the amount of force needed to lift the load?
The more pulleys and ropes you add the easier it is to lift
A simple machine that has a grooved wheel that holds a rope or a cable is a?
A Pulley This works by changing the direction of force around the wheel, which also provides reduced friction to the ropes movement. -Examples Include: Window Blinds, Flagpole pulleys, rock climbing pulleys, and some clotheslines.
