When using a free pulley what is the relationship between the distance you have to pull and the force you need to apply?

There is no direct relation between those 2 values, you can pull as long as there is rope using the same steady force...
But, the Force x the Distance pulled equals the Work (energy) spent (FxD = W).
If you divide the Work by the duration of the pull, you'll get the average Power consumed
F x D = W
W / t = P, therefore F x D/t = P => F x V = P where V is the speed
The power is the force x the speed
You can use those equations to dimension an electrical engine to lift the charge using the pulley for example

In a free pulley system, the relationship between the distance you have to pull and the force you need to apply is inversely proportional. This means that as you increase the distance you need to pull, the force required decreases. Conversely, if you decrease the distance you need to pull, the force required increases. This relationship is a result of the conservation of energy principle in a pulley system.

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.
Why was the pulley invented?
to gain mechanical advantage. So you dont need to apply as much force to move something. A pulley halves the ammount of force needed, but you need to pull a rope twice as far to move the object the same distance.
What kind of pulley changes the direction of input force but does not change amount of force you apply?
A single pulley alters the direction of the input but confers no mechanical advantage.
How does pulleys work?
Pulleys can multiply the force you apply. Example: I pull down on a pulley with TWO Pulleys THREE supporting Strands and the force is Multiplied by a factor of TWO, but you have to pull TWICE the length of Rope as the Distance the Object is Raised. Therefore you can LIFT more WEIGHT than you normally could.The relationship of Supporting Strands to the Force Multiplier is:(the number of Supporting Strands) - 1So a Pulley system with 5 Supporting Strands with Multiply YOUR input Force by 4 times. This type of System is referred to as "Block and Tackle".
What is the relationship between creme brulee and quantum physics?
Nothing. Quantum physics is a theoretical type of physics that doesn't apply to physical objects.

This distance is called the 'Thinking Distance'.
Why you use idler pulley?
To apply tension

What is the trade off between mechanical advantage and the distance within pulley systems?
Mechanical advantage: you can use some method (eg, lever or pulley wheels) to move an object which otherwise would be too heavy, or jammed. The trade off is that you can't get away with using less work - the reduced force you need to apply is compensated by the fact you have to move your force throgh a proportionately larger distance.
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?
You will need 8 drops of chain. So the operator must apply 250 newtons to the 8th drop. The other 7 drops of chain must be reeved through the pulley system.

A single pulley alters the direction of the input but confers no mechanical advantage.
How do you apply standard deviation to normal curve?
The distance between the middle and the inflection point is the standard deviation.
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 difference between direct and indirect measurement in surveying?
Direct Measurement: Apply the instrument directly to the unknown quantity. E.g. Taped distance, direction measured with a theodolite Indirect Measurement: Determined from its relationship to direct measurements. E.g. height difference determination in trigonometric leveling
