Here's why:

* Fixed pulleys are attached to a stationary point, like a ceiling or a beam.

* They change the direction of the force applied, but they don't change the magnitude of the force.

* This means that if you apply a force of 100 Newtons to the rope, you will also get a force of 100 Newtons at the other end of the rope.

However, the real advantage of a fixed pulley lies in its ability to change the direction of the force. This can make it easier to lift heavy objects, as you can pull downwards instead of upwards.

Example: If you are lifting a weight with a fixed pulley, you only need to pull downwards with a force equal to the weight of the object, rather than lifting it directly upwards.

Important Note: A fixed pulley does not multiply the force. It only changes its direction.
