Does a pulley have a fulcrum?
No, a fulcrum is the pivot point for a lever
Does a pulley use a fulcrum?
No. A fulcrum is the pivot point of a lever.
How is a pulley like 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.
What is the part called where the rope lies on a pulley?
The grooves on the pulley wheel
What is the definition of simple pulley?
A simple pulley is one fulcrum with no mechanical advantage.

Why is a rigid bar that rests on a fixed point called a fulcrum?
The rigid bar is not called a fulcrum! And, by the same token, why is the bar called a bar?
What are parts are of a lever?
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum

What simple machines will not work without a fulcrum?
A single pulley
Where is the load arm on a pulley?
The load arm is the radius of the pulley. This is the distance from the fulcrum to the load-carrying side of the rope.
The part of a rope from the pulley to the effort is called an?
effort arm
