The effort on a can opener is applied at the handle, where the user grips and turns it to puncture and cut through the can's lid. This motion typically involves a lever mechanism that amplifies the force applied, allowing the user to effectively open the can with relatively little effort. The design leverages mechanical advantage, making it easier to exert force on the can's metal.
In a can opener, the resistance force is the force required to open the can, applied by the person using the can opener. The effort force is the force exerted by the person to operate the can opener. The fulcrum is the pivot point around which the can opener rotates to open the can.
The fulcrum is the pivot point where the bottle opener rotates, typically located near the base of the bottle opener. The effort is applied by the user at the handle end of the bottle opener to lift the bottle cap. The load is the resistance provided by the bottle cap, which is located at the other end of the bottle opener.
A paint opener is a class 3 lever because the effort is applied between the load and the fulcrum.

The fulcrum on a can opener is where the hook meets the lip of the can. The can opener is a class 1 lever.
A bottle opener is a second-class lever because the load (the cap of the bottle) is positioned between the fulcrum (the point where the opener rests on the bottle cap) and the effort (the force applied to lift the cap). In this setup, the effort arm is longer than the load arm, which increases the effectiveness of the force applied to remove the bottle cap.
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.
A can opener primarily incorporates a lever and a wedge. The lever is used to apply force to the lid, while the wedge, often in the form of a sharp blade, cuts through the metal of the can. Together, these simple machines enable the effective opening of a can with minimal effort.
A manual bottle opener is a type of lever, which helps to amplify the force applied to open a bottle by providing a mechanical advantage. The handle acts as the effort arm, the bottle cap as the load, and the pivot point in the middle serves as the fulcrum.
