What is the formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
Is a well a fixed pulley or a movable pulley?
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.
A person does 50j of work to lift a crate using a pulley. the pulley's work output is 42j. What is the pully's mechanical efficiency?
The mechanical efficiency of the pulley is calculated as: (Work output / Work input) * 100%. In this case, it would be (42J / 50J) * 100% = 84%. The pulley is 84% efficient at converting input work into output work.
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
A fixed pulley is stationary and changes the direction of the force applied, making it easier to lift an object. A moving pulley is attached to the object being lifted, reducing the force needed but requiring a longer distance to be moved. Both types of pulleys reduce the amount of work needed by spreading it out over a longer distance or making it easier to lift the load.
Why do you find a pulley on a well?
A pulley on a well is used to help lift water or objects from the well. By using a pulley system with a rope and bucket, it makes it easier to raise heavy loads from deep wells by distributing the force needed to lift them.
How does a well pulley work?
It works much more effectively, and with greater dedication, focus, and commitment, than an ailing pulley does.

What is the function of pulley?
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.

What is the name of the pulley used to pull a bucket out of a water well?
The type of pulley used to pull a bucket out of a water well is typically referred to as a "well pulley" or a "well bucket pulley." This type of pulley is specifically designed for lifting objects out of wells and is often made of durable materials such as steel or iron to withstand the weight of the bucket and its contents. Well pulleys are commonly attached to a rope or chain system to facilitate the lifting process efficiently.
How does the work you get out of a pulley compare with the work you put into it?
The WORK is the same. Work = force times distance. If the pulley allows you to pull half as hard, you will have to pull over twice the distance (length of rope), making the same total work. (Ignoring friction; you would actually have to do slightly more work to overcome the friction in the pulley.)
What is a single moveable pulley?
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
Can your car work with a malfunctioning idler pulley?
The Answer is no.
Do pulleys make you work less?
No. If you are, say, lifting a weight the amount of work done is the same whether you use a pulley or not. However, you may not be able to actually lift the weight unless you use a pulley. But the amount of work done will be the same with or without the pulley.
Can you replace just the pulley on the power steering pump for a 98 Plymouth voyager?
Well!? I am just going through the hell with this problem. Pulley is made out of plastic compound - bakelit. You will have to remove a drive shaft in order to take a pump with the pulley out. You need a special pulley remover to do the job for you - on your work bench. Another option is braking the old pulley and chipping the pieces out. Mounting a new pulley is a another issue. You will need a compressor and a pneumatic gun to mount a new pulley on the shaft of the PS pump.
