A pulley is a simple machine that uses a wheel and rope to lift or lower objects. A lever is a simple machine that uses a rigid bar resting on a pivot to help move objects with less force. Both pulleys and levers are tools that make it easier to lift heavy objects or move loads.
No, a fulcrum is the pivot point for a lever
A pulley has an axle or pivot just like a lever has a fulcrum. Just as a lever tilts across a fulcrum and the fulcrum bears all the weight, a pulley rotates around its pivot/axle the same way. So in essence, a pulley is a lever wrapped into a wheel, with its fulcrum in the center.
A pulley and a lever are both simple machines that help to make work easier by changing the direction or magnitude of a force. They both utilize the principle of mechanical advantage to multiply force or distance.
The ancient Greek mathematician Archimedes is credited with discovering the principles of the lever and the pulley. His work on these simple machines laid the foundation for the field of mechanics.
A pulley is a class 1 lever because the fulcrum (pivot point) is between the load (object being lifted) and the effort (force applied to lift the load).
maybe the pulley but not the lever he invented the pulley but not the lever
No, The Greek Scientist who founded the Lever and Pulley is Archimedes.
Pliers are a lever
wedge lever
lever at crank, connected by chain to lever at rear wheel
A lever is an adaptation of a stick or tree branch. A pulley is an adaptation of a wheel.
