Sketch a pulley system in which the applied force would move a distance of 120 cm and the load would move only 20 cm?
In a pulley system with a mechanical advantage of 6 (6:1), where the applied force moves 120 cm, the load would move only 20 cm. This can be achieved by having 6 pulleys and redirecting the rope through each of them to multiply the force and reduce the distance traveled by the load.

How does the input distance of a single fixed pulley compare to the output distance?
The input distance of a single fixed pulley is equal to the output distance. The pulley system doesn't provide a mechanical advantage in terms of distance but does change the direction of the force applied.
Actual mechanical advantage of a pulley?
The actual mechanical advantage of a pulley system is calculated by dividing the output force by the input force. It is the ratio of the load force being lifted to the force applied to lift it. This value indicates how much the pulley system amplifies the force applied.
How do you calculate the distance the rope needs to be pulled to lift the load?
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.
What is the trade off of a pulley?
A pulley can trade off distance for force. By increasing the number of pulleys in a system, you can reduce the amount of force needed to lift an object in exchange for a longer distance over which the force must be applied.
What is the tension equation for a pulley system?
The tension equation for a pulley system can be calculated using the formula T 2F, where T is the total tension in the system and F is the force applied to the pulley.

What is the tension formula for a pulley system?
The tension formula for a pulley system is T 2F, where T is the tension in the rope and F is the force applied to the system.
What are variables for a pulley?
Some variables for a pulley system include the radius of the pulley, the force applied to the pulley, the tension in the rope or belt, and the acceleration of the system. Each of these variables can affect how the pulley system functions and can be used to calculate mechanical advantage or efficiency.
Where is force applied in a pulley?
Force is applied to a pulley at the point where the rope or cable passes over the wheel or sheave. This force is used to lift or move objects by leveraging the mechanical advantage of the pulley system.
How could a pulley multiply the distance but not the force of the effort?
A pulley system can multiply distance but not force of the effort because the force applied is spread out over a greater distance as the rope is fed through the pulleys. This enables the user to move an object a longer distance with less force, as the trade-off is a decrease in the force required for each unit of distance traveled.
How far must the effort rope of a single fixed pulley move to raise a resistance 4m?
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.
How would you describe a single pulley system?
A single pulley system consists of a wheel with a groove and a rope, allowing a force to be applied to lift or move an object. It changes the direction of the force applied, making it easier to lift heavy loads by distributing the force needed to lift the object.
What is the mechanical advantage of the pulley system If you pull the rope in a pulley system 6 metres to lift a load 2 metres?
The mechanical advantage of the pulley system in this case would be 3. This is calculated by dividing the distance the rope is pulled (6m) by the distance the load is lifted (2m).
