Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?

Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.

∙ 11y agoalthough it probably wouldn't change the force needed very much, a single pulley does in fact decrease the amount of force needed to lift a object. More pulleys=less force needed

How many pulleys are needed to lift a heavy load?
It depends on the size of the load and your strength. Archimedes pull a trimaran up onto the shore all by himself using a system of twenty pulleys.

What objects with equal amounts of positive and negative charge are said to be electrically?
An object with equal amounts of positive and negative charge is electrically neutral.
The amount of friction divided by the weight of an object forms a unitless number called the ... of friction?
coefficientThe amount of friction divided by the weight of an object forms a dimensionless number called the coefficient of friction.

How does the number of supporting ropes on a pulley affect the amount of force needed to lift the load?
The more pulleys and ropes you add the easier it is to lift
Explain why an infinite amount of pulleys doesn't give an infinite mechanical advantage?
An infinite number of pulleys has an infinite amount of friction, which means you cant move the system no matter how hard you pull.

How much number's excist?
There is no way to determine the amount of numbers that exist. Unlike physical objects, numbers are not finite. There is literally no end to the amount of numbers that can exist.
What is equal to the ideal mechanical advantage of a pulley system?
The ideal mechanical advantage of a pulley system is two times the number of pulleys in the system. This is the amount of force required to get the system moving.
