Pulleys and gears

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…

This document shows you how to make an effective and useful pulley system. If you study the pictures, you will be able to understand how the ratio of a pulley system is calculated. Understand that the maximum load to the break in a pulley system should not be underestimated. And last but not least I visualized you some systems with different ratios. This is for example useful if you plan to setup longer slacklines.

This set of virtual experiments ask students to explore load and effort forces, calculate mechanical advantage and discover the relationship between the number of pulleys, length of rope and the force needed to lift a mass.

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.

Download this stock vector: A movable pulley is a pulley that is free to move up and down, and is attached to a ceiling or other object by two lengths of the same rope, vintage l - 2BTGEE5 from Alamy's library of millions of high resolution stock photos, illustrations and vectors.

The only advantage that fossil-fuelled powered cranes have brought us, is a higher lifting speed

“The ability to observe without evaluating is the highest form of intelligence!” Human beings are the most successful species on Earth only for the reason of their expertise in tools and machines. This activity will teach kids about machines and in detail along with demonstration explains one of the simple prominent kinds of machines.Introduction:One look at something that expresses a thousand words regarding itself. Explaining our kids along with a live implementation of a machine will give…
