it helps because the pressure is on the wheel and you can easily slide the rope over the wheel

What do we use a fixed pulley for?
this is berat writing.we use fixed pulley for lifting load up only by using force on the effort that makes the load lift
What is a fixed pulley?
A fixed pulley is a pulley that is attached to a support. It does not reduce the effort needed to lift the load, but rather changes the direction of the applied force.An example of a fixed pulley would be the rope pulley on a well. This is a fixed pulley because the pulley doesn't move (it is attached to the overhead structure).
When a fixed pulley is used what does the force and the load do?
A fixed pulley allows the direction of the applied force to be varied. It does not change the load.
24lbs of weight hanging on a pulley how much force is needed to lift the weight?
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
How many pulley needed to lift a load?
The number of pulleys needed to lift a load varies based on the size of the load. A very small load can be lifted with just one pulley while large loads may require many pulleys to adequately lift the load.

Would you use a fixed pulley or movable pulley to lift a heavy load?
Fixed if it weighed as less than you, but a movable pulley wouldn't be helpful here. You'd be best with a pulley with multiple supporting ropes.
A fixed single pulley that is used to lift a block does what?
The choices are:A. Doubles the force required to lift the blockB. Decreases the force required to lift the blockC. Makes the block easier to lift by changing the direction of the force needed to lift it.D. Decreases the force required and changes the direction of the force required

What do fixed fixed pulleys always do?
A fixed pulley when used individually, uses more effort than the load to lift the load from the ground. This is what a fixed pulley always does. When attached to an unmovable object e.g. a ceiling or wall, it always acts as a first class lever where the fulcrum is 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 it up and down. The disadvantage is that you have to apply more effort than the load.

How does a pulley help you lift a load?

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.

What are the three kinds of pulley?
1. The fixedpulley - requires more effort than the load. 2. The movable pulley - moves with the load which allows for less effort than load. 3. The combined pulley - effort is less than half the weight of the load
