Does a fixed pulley increase distance output?
No, a fixed pulley does not increase the distance output. It changes the direction of the force applied, but the amount of work input remains the same as the output distance.
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 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 the input force and output force of a pulley?
The input force is the force applied to the pulley by the person or machine. The output force is the force exerted by the pulley to move the load. The output force is typically higher than the input force due to mechanical advantage.
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.
Is a pizza cutter a pulley?
a pizza cutter is not a pulley
What kind of simple machine is cutter?
pulley

What type of pulley would increase the output force?
A pulley system that has multiple pulleys in line with each one having its output drive the next will increase the force. This would be called a tackle pulley.
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

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.
A person does 50j of work to lift a crate using a pulley. the pulley's work output is 42j. What is the pully's mechanical efficiency?
The mechanical efficiency of the pulley is calculated as: (Work output / Work input) * 100%. In this case, it would be (42J / 50J) * 100% = 84%. The pulley is 84% efficient at converting input work into output work.
What type of advantage described the ability of a machine to increase output force?
Mechanical advantage is the greater outputted force than inputted force that is generated by using a machine. One example is pulling a pulley to create a much greater output force on the other side that a person could not lift without a pulley.
How can we analyaze the mechanical advantage of a pulley system?
To analyze the mechanical advantage of a pulley system, you calculate it by dividing the output force (load) by the input force (applied force). The mechanical advantage of a pulley system is equal to the number of rope sections supporting the load. More rope sections mean a greater mechanical advantage.
What are the input arm output arm and fulcrum of a pulley?
The input arm is the distance between the input force and the fulcrum. The output arm is the distance between the output force and the fulcrum. The fulcrum is the fixed point around which the pulley rotates.
