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
The Fast Fours is a simple variation on a standard set-of-fours. The difference is that the far end of the rope is not terminated on the becket of a pulley. Instead it is run through another progress
Friction through Progress Capture Devices (PCDs). This image shows three different devices rigged and loaded as if positioned at the back of a hauling system. We can use the Capstan equation to predict the loss through each
