There more to measured pulley efficiency than just consideration of the physical bearings or bushings on the axle. This report considers the effect of losses within the rope.
Tuomas Pöysti, a good friend of RopeLab, has written this article presenting his thoughts on analysing pulley systems.
There are many ways to tension the guy lines and anchor legs we use in our systems but I’d like to present the one I use most. I will start by mentioning that this works best with
This article explores the basic physics concept of a lever. This concept is then used to calculate mechanical advantage in roped systems. Levers Most people will be familiar with the concept of a lever, however it is useful to
Pulley efficiency seems initially like a simple thing to measure, however it presents an excellent opportunity to consider various aspects of experiment design. Experiment design At face value it would seem that we could simply set up
