simple machine
Lever or wedge
A simple machine is a basic mechanical device that changes the direction or magnitude of a force—the lever, wheel and axle, pulley, inclined plane, wedge, and screw.
These six form the building blocks of all complex machinery.
A crowbar is a simple machine that multiplies the force you apply.
