Do the moveable pulley decreases the input force?
Do the moveable pulley decreases the input force?
What is the input force and output force of a pulley?
The input force is how much force you use to pull on it. The output is what is lifted.
What kind of pulley changes the direction of input force but does not change amount of force you apply?
A single pulley alters the direction of the input but confers no mechanical advantage.
How does a fixed pulley affect the input force?

How does a fixed pulley act as machine?
It changes the direction of the input force only
Do the moveable pulley decreases the input force?
Do the moveable pulley decreases the input force?
What kind of pulley changes the direction of the input force but does not change the amount of the force you apply?
They pulley is applied by the output force and then it is being added on by the input work.

Unlike a fixed pulley a movable pulley multiplies the input force?
True

Does a fixed pulley multiply input force?
no it can't.
Does a moveable pulley multiply the input force?
Yes. The IMA of a movable pulley is 2.
Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
How does a fixed pulley act as machine?
It changes the direction of the input force only
Do all simple machines either reduce the input force or increase the distance over which work is performed?
Simple machines will reduce the input force, but can allow you to travel farther distances. Your'e body is not putting in as much force, your body will allow you to do more work for a longer time....but yes,it decreases the input force.
What is the output force of a movable pulley?
Depends what the input force is and the mechanical advantage of the pulley system If effort force (input force) is 20 pounds in a 6 pulley system (3 fixed,3 movable) then load force (output force) is 120 pounds As 6 times 20 equals 120 pounds
