How Mechanisms Work

A lever works by having a long object over a small/strong object pulling anything that you put the long object under.

A pulley works by putting a rope over a wheel, pulling the other side of the rope which pulls the object that you attached to on the other side.

A gear works by having two circular shapes with teeth and turning them. Turning one, the other one turns with it. Having two gears with two different sizes, the smaller one turns quicker but with less force, and the bigger turning slower with more force.
