A fixed pulley allows the direction of the applied force to be varied. It does not change the load.
Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.
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).
this is berat writing.we use fixed pulley for lifting load up only by using force on the effort that makes the load lift
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

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
a fixed pulley changes the direction you are executing the force in. fixed pulleys are made to work with gravity which makes the work you must use less than if you were lifting straight up and against gravity.
There are two basic types of pulleys. When the grooved wheel is attached to a surface it forms a fixed pulley. The main benefit of a fixed pulley is that it changes the direction of the required force. Another type of pulley, called a movable pulley, consists of a rope attached to some surface. The wheel directly supports the load, and the effort comes from the same direction as the rope attachment.

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.

A fixed pulley is a pulley that is attached to a structure and does not move;changes the direction of the effort force used to life a load by a person or a spring scale and if you use a spring scale then you will need a person to pull the spring scale done to see how far she/he pull it A moveable pulley is a pulley that supports the load and is not fixed in place;reduces the amount of effort force needed to pull to lift the load when she/he pulls the spring scale then it will tell she/he pulls it.
