What Is A Double Pulley?
A double pulley is a type of pulley system that consists of two pulleys mounted on a common axle or shaft. The two pulleys are typically of different sizes, with the larger one known as the drive pulley and the smaller one known as the driven pulley.
A belt or rope is wrapped around both pulleys, and when the drive pulley is rotated, it causes the driven pulley to rotate as well. This arrangement allows for mechanical advantage, where force can be multiplied or speed can be reduced, depending on which pulley is used as the input and which is used as the output.

How Double Pulleys Work?
When the drive pulley is rotated, it causes the rope or belt to move along the pulleys. The load attached to the rope or belt moves in the opposite direction to the movement of the rope or belt. The amount of force required to lift the load is determined by the size of thepulleys and the ratio between them.
If the drive pulley is larger than the driven pulley, the load will be lifted with less force, but at a slower speed. If the driven pulley is larger than the drive pulley, the load will be lifted with more force, but at a faster speed.

Advantages
Advantages Of Double Pulley
Double pulleys offer several advantages over other types of pulley systems, including:
Mechanical advantage
They provide a mechanical advantage, which means they can multiply the force exerted on a rope or belt, making it easier to lift heavy objects.
Versatility
It can be used for a wide range of applications, from simple machines such as cranes and hoists to more complex systems such as elevators and conveyor belts.
Efficiency
More efficient than other types of pulley systems because they require less force to lift heavy objects.
Flexibility
More flexible than other types of pulley systems because the distance they can lift the load is not limited by the length of the rope or belt.
