It seems like your question got cut off. If you're asking about the output force or mechanical advantage of a pulley system, it generally depends on the configuration of the pulley. For a simple pulley, the output force can be equal to the input force, but if it's a compound pulley system, the output can be greater than the input depending on the number of ropes supporting the load. Please provide the complete question for a more accurate answer!

If the input force on a pulley is 3 N and the output force is also 3 N what is its mechanical advantages?

If the input force on a pulley is 3 N and the output force is also 3 N what is its mechanical advantage?

The mechanical advantage of the pulley system in this case is 1:1. This means that the input force and output force are equal, resulting in no mechanical advantage gained.


Find the output force exerted by a moveable pulley if the input force is 50 N?

The output force exerted by a movable pulley is equal to the input force applied. Therefore, if the input force is 50 N, the output force exerted by the movable pulley will also be 50 N.


What is the output force exerted by a move-able pulley if the input force is 50 N?

The output force exerted by a moveable pulley when the input force is 50 N would be 50 N. Since a moveable pulley changes the direction of force but not its magnitude, the output force will be equal to the input force.


If the input force on a pulley is 3 N in the output force is also 3 N what is the mechanical advantage?

In this case, the mechanical advantage is 1:1 because the output force is equal to the input force. Mechanical advantage is calculated by dividing the output force by the input force. Since they are both 3 N, the mechanical advantage is 1.


How much input force is required to lift an 11000 N beam using a pulley system with a mechanical advantage of 20?

11,000/20=550newtons


What is the efficiency of the pulley system. A pulley system is used to lift a 2000 newton engine up a distance of 3 meters. The operator must apply a force of 250 newtons to the chain of the pulley s?

The efficiency of the pulley system is calculated as the ratio of output work to input work. In this case, the output work is the work done in lifting the engine (2000 N * 3 m), which is 6000 joules. The input work is the work done by the operator (250 N * 3 m), which is 750 joules. Therefore, the efficiency is 6000/750 = 8 or 800%.


What is the output force exerted by a movable pulley if the input force is 50N?

Because the mechanical advatage of a movable pulley is always two you multipy the input force times two. So 50 * 2 = 100N


What is the output force of a movable pulley?

Depends what the input force is and the mechanical advantage of the pulley system If effort force (input force) is 20 pounds in a 6 pulley system (3 fixed,3 movable) then load force (output force) is 120 pounds As 6 times 20 equals 120 pounds


What system requires the smallest input force to lift a 2500 N load?

A system with a mechanical advantage greater than 1 will require a smaller input force to lift a load. To lift a 2500 N load with the smallest input force, a pulley system with a mechanical advantage of 2 would only require an input force of 1250 N.


Unlike a fixed pulley a movable pulley multiplies the input force?

True
