Force and Resistance
if it is a fixed pulley, itself doesnt move. If it is a rotating pulley, its joint probably doesnt move.
pulley
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 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, 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.
A fixed pulley is a wheel and axle attached to an anchor point that does not move. An example of this is in a single pulley system where the rope goes up to a hanging pulley, over the wheel of the pulley and back down to the ground again.
The load will move upwards.
