That is not always true. Sometimes a fixed pulley is more useful.
A fixed pulley changes the direction of the input force without changing its magnitude. It can make it easier to lift or move an object by allowing the force to be applied in a more convenient direction.
The three types of pulleys are fixed pulley, movable pulley, and compound pulley. Fixed pulleys are attached to a stationary object, movable pulleys move along with the load, and compound pulleys combine both fixed and movable pulleys to provide mechanical advantage.
A block and tackle pulley system consists of one fixed pulley and one moving pulley working together to lift heavy loads with less effort. For example, a flagpole typically uses a block and tackle pulley system to raise and lower the flag.
A fixed pulley changes the direction of the force applied, making it easier to lift heavy objects. It also doesn't provide any mechanical advantage in terms of reducing the amount of force needed to lift an object, but it can make the lifting process more manageable.
A fixed pulley requires more effort than the load to lift it from the ground. This type of pulley changes the direction of the force applied but does not provide any mechanical advantage in terms of reducing the effort needed to lift the load.
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.
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

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.

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.

one example of a single pulley is a clothes line . another example is a ................ what do you think because I need to think more on this.
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 .
