Question

What is the first class lever

Answer 1

Answer:

First class levers have the fulcrum between the force and the load. 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. By this means you are reducing the effort required, this is what first class levers do best. Other examples of first class levers are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance.
