A single fixed pulley provides a mechanical advantage of 1, meaning the distance the effort rope must move is equal to the distance the resistance is raised. Therefore, the effort rope must move 4 meters to raise the resistance 4 meters when using a single fixed pulley.
Thew pulley changes the direction of the effort force.
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.
To make a single fixed pulley work, you need to apply an input force to one end of the rope. The pulley redirects the force in the opposite direction, allowing you to lift or move an object with less effort. The mechanical advantage of a single fixed pulley is 1, meaning the output force equals the input force.
A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
A compound pulley increases your effort force by spreading it out over multiple rope segments and pulleys. This system allows you to lift heavier loads with less force compared to a single fixed pulley.
In a fixed pulley system, the effort rope must move the same distance as the resistance (4m) in order to raise it by the same amount. This is because the fixed pulley changes the direction of the force applied, but does not provide any mechanical advantage in terms of distance.

Single Pulley
A single fixed pulley is a type of pulley that is attached to a fixed structure, such as a ceiling or a beam. It changes the direction of the force applied to lift an object, making it easier to lift heavy loads by redirecting the force needed. However, it does not provide any mechanical advantage in terms of reducing the effort required to lift the object.
Movable pulley is attache to the object you are moving while Fixed Pulley changes direction of the applied force.LaDy_caRoLi "Christine carren alcantara"
