The main force that makes a can opener work is manual force applied by the user to turn the handle. This force is translated into rotational motion, which causes the cutting wheel to rotate and pierce the can lid. Additionally, there is a mechanical advantage in the design of the can opener to make opening cans easier and more efficient.
A can opener is a class 2 lever, where the load (the can lid) is between the fulcrum (the turning point) and the effort (your hand). The mechanical advantage gained from this arrangement helps to make it easier to open cans.
The can opener is a compound machine, typically combining levers and gears, to make it easier to open cans by multiplying force and reducing the effort needed.
