yes,a fulcrum needs a bar to lift an object but a pulley does not need a bar
No, a pulley does not have a fulcrum. A pulley is a simple machine that uses a wheel with a groove to change the direction of a force. A fulcrum is a pivot point that helps a lever rotate.
No, a pulley does not use a fulcrum. A pulley is a simple machine that utilizes a wheel and axle to redirect the force applied to it. It works by changing the direction of the force, not by pivoting around a fulcrum like a lever.
The input arm is the distance between the input force and the fulcrum. The output arm is the distance between the output force and the fulcrum. The fulcrum is the fixed point around which the pulley rotates.
The point on a pulley where it pivots is called the axle or the shaft. It serves as the point of rotation for the pulley system.
Yes, a pry bar pivot can be considered a type of fulcrum. A fulcrum is a point around which a lever pivots, and in the case of a pry bar, the pivot point acts as the fulcrum to help generate force for lifting or prying objects.

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 input arm is the distance between the input force and the fulcrum. The output arm is the distance between the output force and the fulcrum. The fulcrum is the fixed point around which the pulley rotates.
The rigid bar is not called a fulcrum! And, by the same token, why is the bar called a bar?

Yes, a pry bar pivot can be considered a type of fulcrum. A fulcrum is a point around which a lever pivots, and in the case of a pry bar, the pivot point acts as the fulcrum to help generate force for lifting or prying objects.
A pulley and a lever are both simple machines that can be used to change the direction or magnitude of a force. They both rely on the principle of applying force to make work easier by trading distance for force. A lever uses a fulcrum to pivot and magnify force, while a pulley uses a wheel and axle to redirect and change the direction of force.

A single 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.
