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.

simple and complex.
A forklift generally gets it mechanical advantage from hydraulic rams, not pulley systems...

Short circuits are typically associated with electrical circuits. Pulley systems are associated with mechanical cable and pulley lifting systems. The two are so different that the question does not make sense. Please restate the question.
Ropes or cables run around pulleys and each pulley wheel reduces the pulling effort.
because it helps lift it with the pulley doing all the work.
The different types of Pulley Systems include:FixedMovableCompound
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....
One can find different images and diagrams of pulley systems online at Google images. One can also find it on a website called Climate Changes Matters which is a resource that teachers commonly use.
Yes, I am pretty sure that such pulley systems exist.
