What are some good questions about a pulley?

If someone needs to use a pulley system to move or pull an object, there are a few important questions to ask about the pulley system. It is important to know, how much force the pulley system can withstand, and if the straps on the pulley system can secure the object you are moving.


How does a movable pulley move?

Force and Resistance


A pulley system is used to lift a 2000 newton engine up a distance of 3 meters How much force will the operator have to apply if the mechanical advantage of the pulley system is 4?

A pulley system is used to lift a 2,000 newton engine up a distance of 3 meters. How much force will the operator have to apply if the mechanical advantage of the pulley system is 4? mechanical advantage = 500 newtons.


What are the differences between a fixed pulley and a moving pulley and how do each of them change work?

The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.

What is true of a real machine that enables a person to move a heavy object with little applied force?

I'd go with simple machines. Specifically, probably a pulley (or pulley system).

Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?

A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.

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

The answer will depend on the configuration of the rope as it goes around the movable pulley and the fixed roller.


Which pulley system can make work easier?

A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.


What does a pulley cause?

When used appropriately, a pulley can be used to reduce the amount of force needed to move an object. By using multiple pulleys, one can change the direction that force needs to be applied to move an object, as well as reducing the amount of force that is necessary through mechanical advantage.
