lever mechanism
Fulcrum-based machine part
A lever mechanism is a simple machine consisting of a rigid bar that pivots on a fixed point called a fulcrum, used to transmit or multiply force.
The three classes differ by where the fulcrum, effort, and load are positioned relative to each other.
Seesaws, crowbars, and wheelbarrows are everyday examples.
The catapult uses a lever mechanism to launch projectiles.
