When used appropriately, a pulley can be used to reduce the amount of force needed to move an object. By using multiple pulleys, one can change the direction that force needs to be applied to move an object, as well as reducing the amount of force that is necessary through mechanical advantage.

What forces act on a pulley?
The forces acting on a pulley are tension forces exerted by the ropes or cables pulling on it. These tension forces cause the pulley to rotate and transfer motion and forces between different parts of a system. Frictional forces may also act on the pulley, depending on the surface it is in contact with.
A ball of mass m is tied to a string that is wrapped around the outside of a pulley. The pulley which is a uniform solid disk also has a mass m and the pulley rotates without friction about the axle t?
The tension in the string will be equal to the centripetal force required to keep the ball in circular motion. This tension will then cause the pulley to rotate. The angular acceleration of the pulley can be determined by utilizing torque equations with the moment of inertia of the pulley and the tension in the string.
What is the relationship between the torque on a pulley with mass and its rotational motion?
The torque on a pulley with mass affects its rotational motion by determining how quickly it accelerates or decelerates. A greater torque will cause the pulley to rotate faster, while a smaller torque will result in slower rotation.
Why is friction a nuiscance in a pulley?
Friction in a pulley can reduce the efficiency of the system by causing energy loss in the form of heat. It can also cause wear and tear on the pulley and the rope or belt running over it, leading to maintenance issues and reduced lifespan of the components. Overall, friction in a pulley can hinder smooth operation and reduce the overall performance of the system.
What is the velocity ration of a pulley?
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
What causes a pulley to wobble?
Things that might cause a pulley to wobble: The pulley is bent. The shaft the pulley is on is bent. The pulley is mounted crooked.
Does the idler pulley cause rough idling?
No. The idler pulley only maintains tension on the serpentine belt. A faulty idler pulley can cause noise and a loose tensioner arm can cause belt slipping but other than having a similar name, it has nothing in common with engine idling.
Would a bad gasket on your tension pulley cause your belt to not run smooth?
there are no gaskets on a tension pulley ther is however a spring and yes it can cause the belt not to run smoothly
What does the idler pulley on a Jeep 4.0L connect to on the motor?
The idler pulley is a unit connected to the engine via a brace or bracket. This part merely routs the belt in a certain direction and, if bad, will cause a failure of the total serpentine system or cause belt wear as with any bad pulley in the system.
How do you take a supercharger pulley out?
This all depends on what type of supercharger it is. If you have an Eaton supercharger it is possible that it might be a pressed on pulley. If this is the case then you will need a pulley puller. If the supercharger is a Vortech, Paxton, or ProCharger they all use key ways. So all you need to do is take the bolt off and the pulley might come off. Some times the pulley will not slide off so a pulley puller will work. Or you can heat up the shaft which will cause the pulley to expand and it will then slide right off. DO NOT use a screw driver or any force to pry it off. This can cause damage to the bearings.
What would cause the serpentine belt on a 1999 Chevy Malibu to melt?
frozen pulley
What could cause noise on a 2000 impala serpentine belt pulley?
The belt is slipping.
What would cause the crankshaft pulley to lock up on a Lexus gs 300?
Crankshaft pulley turns with the crank, if it won't turn at all, something internally is broken.
Why does a 1991 Ford Expolorer make a whirring or spaceship like sound from the area of the idler pulley during idling and acceleration even though the idler pulley has been replaced?
you have another pulley and that the tensioner pulley and it is spring loaded and it keeps the belts and pulleys tighten .If its bad it will cause that sound
What forces act on a pulley?
The forces acting on a pulley are tension forces exerted by the ropes or cables pulling on it. These tension forces cause the pulley to rotate and transfer motion and forces between different parts of a system. Frictional forces may also act on the pulley, depending on the surface it is in contact with.
Is a pulley a type of a simple machine?
it is by changing the direction of the input force on the object on studyisland
What would cause a supercharger to over boost?
A supercharger is controlled by its pulley size. The smaller the supercharger drive pulley is, the higher in boost pressure you will see. Now if you go with a larger crank pulley, this too will cause you to see more boost. So, in all honestly, the only way to really over boost your supercharger is when you mess around with the pulleys.
