When two pulleys are used together in a system, they create a mechanical advantage by distributing the load over multiple ropes and pulleys. This reduces the amount of force needed to lift an object, making the task easier.
You can increase the mechanical advantage of a pulley system by adding more pulleys to the setup. As the number of pulleys increases, the mechanical advantage also increases. This allows you to lift heavier loads with less force.
The pulley formula used to calculate the mechanical advantage of a system involving pulleys is MA 2n, where MA is the mechanical advantage and n is the number of pulleys in the system.
There are three main types of pulleys: fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are attached to a structure and change the direction of the force applied. Movable pulleys are attached to the object being moved and provide mechanical advantage. Compound pulleys combine fixed and movable pulleys to increase both the weight capacity and mechanical advantage.
When two pulley systems work together, they create a mechanical advantage by distributing the load's weight across multiple ropes and pulleys. This reduces the amount of force needed to lift a heavy load, making it easier to lift.
Mechanical Advantage [achieved through levers or pulleys]

By increasing the effort distance on the machine.
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.

Mechanical Advantage [achieved through levers or pulleys]
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
The number of pulleys needed to lift 300 lbs depends on the desired mechanical advantage. A simple pulley system can provide a 2:1 mechanical advantage, meaning you would need two pulleys to effectively lift the weight with half the force. However, if you want to lift the 300 lbs with a lighter force, you can add more pulleys to increase the mechanical advantage, but this will also require more rope length. Ultimately, the exact number of pulleys will depend on the configuration and the amount of force you can exert.
A system with three or more pulleys would provide the maximum mechanical advantage. As the number of pulleys increases, the mechanical advantage also increases, making it easier to lift heavy loads.
Assuming they are all part of the torque-multiplier, and the hauling end is moving parallel with the load end, the advantage is 4:1.
The three types of pulleys are fixed pulleys, movable (or movable) pulleys, and compound pulleys. Fixed pulleys change the direction of the force applied, movable pulleys provide a mechanical advantage by reducing the force needed, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.
