if it is a fixed pulley, itself doesnt move. If it is a rotating pulley, its joint probably doesnt move.
pulley
The part of a pulley where the rope lies is called the groove or the sheave. This is the part of the pulley that provides the surface for the rope to run along while the pulley rotates.
Force and Resistance
A fixed pulley is attached to something that does not move. This type of pulley changes the direction of the force applied but does not provide any mechanical advantage in terms of reducing the effort needed to lift the object.
No.
Yes, for example you would want to move a gear so you would pull on one side of the pulley and it could get where you want it to get.
A pulley is used to move a heavy weight. You can use a pulley to lift something that you can't lift alone.
A sheave or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. (A sheave is actually part of the pulley system.)
A well is a fixed pulley. It changes the direction of the force applied to lift a bucket of water, but it does not move itself.
Loosen the tensioner pulley. Put the belt around the alternator pulley and the tensioner pulley. Move the tensioner pulley to the right until the belt is tight. Tighten the tensioner pulley.
yes... the outer part is the wheel and the part that the string wraps around is the axle
Yes, a pulley can move a load both sideways and upwards with the use of multiple pulleys and appropriate rigging configurations. By adjusting the angle of the pulleys and the direction of the force applied, it is possible to move a load in various directions using a pulley system.
