That is not always true. Sometimes a fixed pulley is more useful.

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
What is an example of a block and tackle pulley?
a combination of one or more fixed pulleys and one or more movable pulleys such as a crane
Why might you want use a single fixed pulley?
if you use a double fixed pully, it could make the rope or wire haver that much more preasure
Does a tire or pulley have more friction?
A tyre has more friction than a pulley.
What are some pulleys?
Simple pulley. Compound pulley. The reel is composed of two or more pulleys.
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
What is the feature of fixed-moveable bridge?
There is no such thing as fixed-moveable bridge in dental care. There is, however, a fixed bridge that is used in dental care. This is a prosthetic device that is used to replace one or more teeth that are missing in the human mouth. A fixed bridge attaches to teeth that are positioned on opposite ends.
How is a fixed pulley different from a movable pulley?
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
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.

What are 2 examples of a single pulley?

What is the ideal mechanical advantage of a fixed pulley raising a 1 kg can of paint a distance of 10 m?
The mechanical advantage doesn't depend on the distance the load moves, any more than it depends on the color of the paint in the can. If the pulley is hanging from the ceiling and you pull down, then the ideal MA is 1 . If the rope is fixed to the ceiling, the pulley rides on it, and the load is hanging from the pulley, then the ideal MA is 2 .
