pulley noun [C]. âº a âpiece of âequipment for âmoving âheavy âobjects up or down, consisting of a âsmall âwheel over which a ârope or âchain âattached to the âobject can be âeasily âraised or âlowered: The âblocks of âstone had to be âlifted into âposition with a âsystem of pulleys.
A pully is simply a circular lever. The same amount of work is required, but you exchange one unit for another. To lift 10 pounds one foot requires 10 foot-pounds of energy. Using a pulley system, you may only have to lift the apparent weight of 1 pound, but you'd have to pull 10 times more rope.
