pulleys are used in everyday life in many different situations and mechanisms. This is understandable because pulleys when used and set up correctly can lift or move a weight that is much greater than the force exerted upon the pulley. they are used in crane systems.
The amount of force required depends on the leverage employed by using the bar.
50 kg (on Earth) weighs about 110 pounds. If you're using a simple, singlepulley with a rope passing over it, then that's the pull you need on the rope tolift the bundle of shingles. If you're using a block and tackle arrangement ofmultiple pulleys, then you'll get away with much less pulling force on the rope,but you'll have to pull the rope much farther.
11,000/20=550newtons

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.

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.

11,000/20=550newtons
11,000/20=550newtons
The Mechanical Advantage is the ratio of the force needed to lift an object using the simple machine divided by the weight of the object
Measure how much it can lift.
350/5 = 70 Newtons. Force is not a function of distance but work is
