PULLEY

1. FIX PULLEY

A fixed pulley is a wheel that has a groove around it into which a rope, chain or belt fits. It rotates around an axle that is fixed to an inmobile surface.

A fixed pulley is ballanced when the effort F is equal to the resistance of the load, R:

       F=R

2. MOVABLE PULLEY

A movable pulley is a set of two pulleys- one is fixed while the other can move in a linear direction.

A movable pulley is balanced when it satisfies this equation:
       
            R
F = -----
        2

3. COMPOUND PULLEY

This is a system of fixed and movable pulley, often called block and tackle.

        R
F=--------
       2n
n= number of movable pulleys.

Exercise

Sammy weighs 9000 kg and Jane weighs 6000 kg. They are both sitting on a seesaw. If

Sammy is seated 6 meters away from the fulcrum, how far should Jane be from the fulcrum?. When solving the problems, draw a diagram of the situation and show your math work.
