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.
A paint opener is a class 3 lever because the effort is applied between the load and the fulcrum.
A bottle opener is a class 2 lever because the output force is between the fulcrum and the input force. In this case, the fulcrum is at one end, the input force is applied on the other end, and the output force is in the middle.
You can push down on a class 2 lever to lift something. This type of lever has the load between the fulcrum and the effort, making it ideal for lifting objects. Examples include a wheelbarrow or a bottle opener.
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.
The type of lever arrangement you're describing is a second-class lever. In second-class levers, the load is placed between the fulcrum and the effort, allowing for mechanical advantage in lifting heavy objects with less force. Examples include a wheelbarrow or a bottle opener.
