A lever is like a handle, whereas a pulley is chain or rope
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.
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).
No, a pulley is not a lever. A pulley is a simple machine that consists of a wheel with a groove and a rope or cable. It is used to lift or move objects by changing the direction of the force applied. On the other hand, a lever is a rigid bar that pivots around a fixed point to help magnify force or change direction.
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.
