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

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.
How does a spring pulley system work?
A single sheeve pully has only one wheel a multiple sheeve pully has more than one wheel.
What three things can a lever do to make work easier?
it's easier to lift things, u wont harm any bones in your body, and it is easy to work a lever
How can a fixed pulley make work easier?
Mechanical advantage is not the only reason one would use a pulley. For instance in a car, pulleys are used to drive alternators and power steering pumps. The use of the pulley and belt is to give power to these devices from the crankshaft. It's a method of transfering kinetic energy to these devices.
Is the best way to straighten steel metal with heat or cold?
heat. the heat will make the steel more malleable and easier to work with
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.

How does a pulley make your life easier?
pulleys allow work to be easier because they lift the stuff up for you but they don't do work for you, it just makes it easier
How does a pulley make life easier?
pulleys allow work to be easier because they lift the stuff up for you but they don't do work for you, it just makes it easier
How does a single pulley make work easier?
by changing the direction of input force
How does a fixes pulley make doing work easier?
it deacreases the input force
How does a fixed pulley make work easier?
A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.
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.
Ma of a pulley?
M.a. of a pulley is how much the machine makes work easier
Does a pulley make work easier by changing the direction of force?
Yes. It can also decrease the amount of work needed in exchange for a long distance.
