What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
What pulleys are attached to an overhead structure and change the direction of force?
Lifting pulleys are attached to an overhead structure, and change the direction of force. You pull down, and the pulley pulls up.
What type of pully can multiply effort force?
Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
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.

What pulleys are attached to an overhead structure and change the direction of force?
Lifting pulleys are attached to an overhead structure, and change the direction of force. You pull down, and the pulley pulls up.
What ways can machine change the direction of the force?
pulleys, levers, pendulums

How is IMA determined for pulleys?
IMA for pulleys is the resistance force divided by the effort force.

' 1 ' is.
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.
