Explanation:

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. ... Other examples of first class levers are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance.

second class

Examples include wheelbarrows, staplers, bottle openers, nut cracker, and nail clippers. A great example of a Class Two Lever is a wheelbarrow. The dirt in a wheelbarrow is the Load, the Fulcrum is the wheel, and the Force is at the end of the handles where a person lifts it.

third class

in a Class Three Lever, the Force is between the Load and the Fulcrum. If the Force is closer to the Load, it would be easier to lift and a mechanical advantage. Examples are shovels, fishing rods, human arms and legs, tweezers, and ice tongs. A fishing rod is an example of a Class Three Lever.
