Pulleys and gears

A fascinating article that describes how a block and tackle (as well as levers and gears) works!

Let us understand the different systems of pulley arrangments and see how we can calculate the effort required to lift the load with a pulley.

Following are the different types of pulleys: #1 Fixed pulley #2 Movable pulley #3 Compound pulley #4 Block and tackle pulley #5 Step pulley

Let's make a DIY pulley! Even though pulleys look simple, they are actually powerful machines that are the foundation of many more complex...

“A movable pulley is one whos block is movable. One end of the cord is fastened to the beam, and the weight is sspended from the pulley, the other end of the cord being drawn by the application of a force P. A little consideration will show that if P moves through a certain distance, say 1 foot, W will move through half that distance, or 6 inches; hence, a pull of 1 pound at P will life 2 pounds at W.” — Hallock, 1905

“Compound pulley designed to use very little power to lift heavy weights.” -Avery 1895

Here we have a 3:1 mechanical advantage. First one end of the rope is attached directly to the load, this is then passed around an…
