Pulleys are one of the most awesome simple machines. It allows you to do superhuman actions with the help of mechanical advantage. Want to lift a car just like Superman? You don’t need any powers. You just need the right amount of pulleys and ropes! You can even lift it with just a finger.
Pulley is a small fixed wheel. Combine it with ropers, you create a system that’s designed to support the movement and change of direction by redirecting force. The more pulleys you use, the less force you need to exert to lift a heavy object.
Can you imagine that this simple machine has been around for more than a millennia? Pulleys have been around since the 2nd millennium BCE. Research says that it’s been used by our ancestors in Mesopotamia.
If you have more than two pulley systems, you can create a block and tackle. It’s created with snatch blocks, the cooler brothers of pulleys. It is a pulley attached to a ring that can be mounted easily. You can place snatch blocks anywhere in a line of rope. This eliminates the need to thread the rope around your pulleys or break your line from either end; making it very convenient.
So, where do we use pulleys with snatch blocks? Of course, it’s used in cargos, sailboats, and ziplines. It’s also available on your gym’s lifting machines.
