Change the direction of force and multiply the force.
Single fixed pulley

pulley
A car engine
It is a system of ropes and wheels that achieve the purpose of making an object easier to lift.
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.

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
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.
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.
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.
The efficiency of a pulley system depends on how it is set up. Be specific.

A Pulley is basically a kind of lever that can be used to change the direction of a force. Properly used, a pulley or system of pulleys can multiply forces
