Chains mesh with sprockets without slipping. A pulley system would need to use higher tension(and suffer higher losses) to avoid slipping.
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.

Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.

When you pull up the flag you pull it up by the rope. The rope has a pulley on it. So the actual poll is not a pulley but it has a pulley system on it
describe a single pulley system
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.
You dont have to use your head you can just use it instead.
Danish bicycle VIN-system was created in 1942.
A vacuum will reduce the air resistance of the rotating pulleys and the movement of the belts. The advantages will however be minimal and hard to measure.Friction is required for the belts to move and be driven by the pulleys. A vacuum will not affect the contact between the belt and pulley.
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
A single pulley system is simple. It's just when a pulley has just one wheel and carries less of a load.
