The fixed pulley
Some curtains use a fixed pulley to open and close the curtain. It is of great help as it changes the direction of a force, making it easier to open and close a curtain, and also the distance moved by the effort is same as the distance moved by the load. So whenever you want a curtain open ,just pull the string that is attached to it.
