To calculate the effort force in a pulley system, start by counting the number of supporting ropes that are directly attached to the movable pulley. Divide the total weight being lifted by this number to find the effort force needed to lift the weight. This assumes an ideal pulley system with no friction or other resistive forces.
To calculate the mechanical advantage of a movable pulley system, you divide the load force by the effort force. The formula is MA = Load Force / Effort Force. The mechanical advantage of a movable pulley is always 2 because the effort force is half the load force when using a system with a movable pulley.
The distance the rope needs to be pulled to lift the load can be calculated using the formula: Distance = (Load weight * Pulley system efficiency) / Effort force applied Efficiency of the pulley system depends on the number of ropes supporting the load. The effort force applied is the force needed to lift the load.
A compound pulley system using multiple pulleys will require the least amount of effort force to lift a weight. The mechanical advantage of a compound pulley system increases with the number of pulleys, reducing the amount of force needed to lift the weight.
In a movable pulley system, the other effort comes from the weight of the object being lifted. The movable pulley reduces the amount of force needed to lift the object by distributing the load between the pulling force and the weight of the object. As a result, the effort needed to lift the object is divided between the pulling force and the weight of the object itself.
A movable pulley reduces the effort force required to lift an object by distributing the force between two sections of the pulley system. This means that you only need to apply half the force compared to a fixed pulley to lift the same load.

To calculate effort force in a lever system, you can use the formula: Load Force x Load Distance = Effort Force x Effort Distance. This formula is based on the principle of conservation of energy in a lever system, where the product of the load force and load distance is equal to the product of the effort force and effort distance. By rearranging the formula, you can solve for the effort force by dividing the product of Load Force and Load Distance by the Effort Distance.
To calculate the force required to lift something with a pulley system, use the formula: Force = Weight / (number of supporting ropes). The weight is the force of gravity acting on the object being lifted. The number of supporting ropes is the number of ropes in the pulley system that are supporting the weight.
In a movable pulley system, the effort force required is half of the weight being lifted. So, to lift a 300 kg weight, you would need to apply an effort force equal to 150 kg.
