Fixed and blank pulleys
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.

Real numbers are madeup of rational and irrational numbers
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.
Some variables for a pulley system include the radius of the pulley, the force applied to the pulley, the tension in the rope or belt, and the acceleration of the system. Each of these variables can affect how the pulley system functions and can be used to calculate mechanical advantage or efficiency.
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.

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
The tension equation for a pulley system can be calculated using the formula T 2F, where T is the total tension in the system and F is the force applied to the pulley.
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.
