Law of the Lever
A lever is a rigid, usually rod-shaped body with a rotatable fixed axis. A distinction is made here between a one-sided and a two-sided lever.
Types Of Lever - Mechanism, Examples
In a first class lever, the fulcrum is located between the load and the effort. When the fulcrum is closer to the load, then less effort is needed to move the load
Second-class levers have the load between the effort and the fulcrum. As an example you see a wheelbarrow. The wheel is the fulcrum, the handles take the effort, and the load is placed between the wheel and the effort.
