∙ 8y agoA pulley is often used in conjunction with a rope or cable to redirect the direction of force. This allows for lifting or moving objects in a more efficient manner by changing the direction of the applied force.
Pulleys can be used to either increase force or redirect the force. A single fixed pulley changes the direction of the force applied, while multiple pulleys in a system can be used to increase the force applied to lift an object.
A changing the direction of force is generally achieved using a fixed pulley or a movable pulley, depending on the specific setup. Both types can redirect the force being applied to a different direction without changing the amount of force.
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
The opposite of a pulley is a fixed point. In a pulley system, the pulley moves to redirect force, while in a static system, the force is applied directly without redirection.
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.

I am not sure what you mean by "a surface that re-directs force" but you could use a pulley to redirect a force from a rope.

A fixed pulley is a type of pulley that is attached to a stationary object, such as a ceiling or wall. It changes only the direction of the force applied to it, without providing any mechanical advantage. Fixed pulleys are commonly used to redirect the path of a rope or cable.
No, a zipper is not a pulley. A pulley is a simple machine that uses a wheel and axle to redirect force, while a zipper is a closure device commonly used in clothing that consists of interlocking teeth.
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.
One single fixed pulley cannot give any mechanical advantage. It can only redirect the direction of the applied force.
Yes, a pulley is a simple machine that uses a wheel and axle to redirect the force applied to it. By wrapping a rope around the wheel, the pulley can change the direction of force needed to lift an object. This change in direction allows for easier lifting of heavy loads.
A rope winds around the pulley so that two ropes hang downwards. Using one side of the rope to apply force causes the pulley to rotate and redirect the force, moving the load upwards even though the pull is applied downwards.
