How does a pulley decrease work?
No, a pulley redistributes the work making it easier but at the end of the pull it will be the same amount of work.
What is moveable pulley?
A fixed pulley is a pulley that is attached to a structure and does not move;changes the direction of the effort force used to life a load by a person or a spring scale and if you use a spring scale then you will need a person to pull the spring scale done to see how far she/he pull it A moveable pulley is a pulley that supports the load and is not fixed in place;reduces the amount of effort force needed to pull to lift the load when she/he pulls the spring scale then it will tell she/he pulls it.
How does a movable pulley make work easier?
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
Will friction in a belt pulley system be reduced when the system is placed in a vacuum?
A vacuum will reduce the air resistance of the rotating pulleys and the movement of the belts. The advantages will however be minimal and hard to measure.Friction is required for the belts to move and be driven by the pulleys. A vacuum will not affect the contact between the belt and pulley.
How do roped elevators work?
pulley system, much like the cabled elevators work.
What are the parts of an elevator and how do they work?
buttons and the ropes and pulley system so the elevator goes up if it gets pulled by the pulley system oh and i am in elementary school and i can answer it
What is double pulley system?
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.

How is a flagpole a pulley system?
When you pull up the flag you pull it up by the rope. The rope has a pulley on it. So the actual poll is not a pulley but it has a pulley system on it
How would you describe a single pulley system?
describe a single pulley system
What is the pulley system for a mousetrap car?
Slows down the power output of the spring on the trap. So that makes it go slower, and go much further.
Where is the tension pulley on 1995 ford windstar?
Will be the only pulley that is spring loaded and not connected to an engine component
How are the double pulley systems different?
Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.
What are some good questions about a pulley?
If someone needs to use a pulley system to move or pull an object, there are a few important questions to ask about the pulley system. It is important to know, how much force the pulley system can withstand, and if the straps on the pulley system can secure the object you are moving.
How does a shoulder pulley work?
The shoulder pulley is actually an exercise device, so it isn't appropriate for your use. You need a wench system, available from industrial supply houses.
What is the mechanical advantage of the pulley system?
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
