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
Does a pulley use less force?
There are a variety of different designs for pulleys, depending upon what you need to do with them. A pulley can be used to change the direction of a force without changing the amount of force that you apply, but there are also pulleys that do reduce the amount of force you have to use to lift something.
What is the advantage of a fixed pulley?
' 1 ' is.
How did the pulley affect the amount of force needed?
A pulley is a force multiplier. (it swaps force for distance).
What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.

How is IMA determined for pulleys?
IMA for pulleys is the resistance force divided by the effort force.
What are names of pulleys with one wheel?
It's called a fixed pulley, the amount of weight on the other end of the rope, is the amount force that you use to pull it up.

What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
What does a pulley cause?
When used appropriately, a pulley can be used to reduce the amount of force needed to move an object. By using multiple pulleys, one can change the direction that force needs to be applied to move an object, as well as reducing the amount of force that is necessary through mechanical advantage.
How can pulleys change direction of the force?
yes
Example to lift a force upward we use 2 pulleys. Then the force becomes half of the force we will have to use with one pulley.HOW?

What do fixes pulleys always do?
change the direction of force
