Simply so, how does a block and tackle pulley system work?
Block and tackle. A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads. The rope is threaded through the pulleys to provide mechanical advantage that amplifies the force applied to the rope.
Also, what are the 3 types of pulleys? Pulleys consist of a wheel that rotates on an axle—which is a rod through the center of the wheel—and a rope, cable, or chain. There are three main types of pulleys: fixed, movable, and compound. A fixed pulley's wheel and axle stay in one place.
Beside this, how do you make a pulley system lift heavy objects?
If you have a single wheel and a rope, a pulley helps you reverse the direction of your lifting force. So, as in the picture below, you pull the rope down to lift the weight up. If you want to lift something that weighs 100kg, you have to pull down with a force equivalent to 100kg, which is 1000N (newtons).
