What type of lever is opening a paint can?

Lifting a paint can lid uses a first class lever because the lid being lifted (the load) is at one end of the lever, the fulcrum (in this case the edge of the paint can) is in the middle) and the force (a person pushing down on the screwdriver outside of the paint can) is at the other end.

### What is the point of using a screwdriver to lift the lid on the paint tin?

In using a screwdriver to lift the lid from a paint tin you are moving the effort over a greater distance than the load. By having the fulcrum (the rim of the tin) close to the lid (the load) a larger force can be applied to the load to open the tin.

What lever is a screw driver?

## Is effort force the same as input?
