How does the minimum input change as you add more pulley to the system?

∙ 9y ago
Adding more pulleys to a system reduces the amount of force required to lift an object. The more pulleys added, the greater the mechanical advantage, meaning the minimum input force needed to lift the object decreases. This is due to the increased number of support points distributing the weight of the object more evenly across the system.

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.
A pulley system always causes the direction of the output force to be the opposite of the input force true or false?
False. A pulley system can change the direction of the force applied, but it does not always result in the output force being in the opposite direction of the input force. The direction of the output force depends on the configuration of the pulleys in the system.
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 is a device that can multiply and change the direction of an input force?
A simple machine like a pulley can multiply and change the direction of an input force. By using multiple pulleys in a system, you can create a mechanical advantage that amplifies the force applied.
What is the formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
No, a pulley system does not change the direction of the input force to be opposite to the output force. Instead, pulleys are used to change the direction of the force to make it easier to lift or move objects.

What kind of pulley changes the direction of the input force but does not change the amount of the force you apply?
They pulley is applied by the output force and then it is being added on by the input work.
What is the formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
What kind of pulley changes the direction of input force but does not change amount of force you apply?
A fixed pulley changes the direction of the input force without changing the amount of force required. It simply redirects the force in a different direction.
What is a movable pulley the input force?
A movable pulley can change the direction of the input force. When a force is applied downwards on one end of the rope, it causes the pulley to move upwards, lifting the load attached to the other end of the rope.
How does the minimum input change as you add more pulleys to the system?
Adding more pulleys to a system reduces the minimum input force required to lift an object. This is due to the mechanical advantage gained through the increased number of pulleys, which effectively distributes the load across multiple support points.
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 must increase as the input force decreases for a pulley?
As the input force decreases for a pulley, the mechanical advantage must increase to compensate. This means that the pulley system must be designed to provide a larger output force relative to the input force in order to lift or move the load. Increasing the number of pulleys or using a pulley system with a higher mechanical advantage can achieve this.
