System Efficiency of Mechanical Advantage Systems
System Efficiency Effect of pulley friction. Most rescue pulleys have an efficiency rating of .75 to .90 (only 75% to 90% of tension is transferred

Progressing to the Next Level in Understanding Mechanical Advantage Using The T-Method
Kudos goes out to Peak Rescue Institute for the help. The purpose of this lesson is to give the student rescuer a more thorough understanding

Mechanical Advantage Progression
Thank you to Peak Rescue Institute for the graphics In this section, students will learn five different MA systems: 1:1, 2:1, 3:1, 4:1, and 5:1.

Functionality of Mechanical Advantage and Considerations
The Mechanical Advantage (MA) systems used in rescue incorporate one of the most elegant simple machines known to man, the pulley. While it is Newtonian

Vectors, Scalars, and Unit-less Values, Part 2
Excerpt from Rigging Lab Academy’s Force Multipliers Video is at the bottom I want to look at how we add vectors together. Previously, we discussed

Vectors, Scalars, and Unit-less Values, Part 1
Full Video is at the bottom A force multiplier is any factor or condition that contributes to the overall stress of a rope system during

Mechanical Advantage, Part 3
Thanks Peak Rescue Institute Full Video at the bottom All right. The next mechanical advantage system in our progression is a five to one mechanical

Mechanical Advantage, Part 2
Thank you Peak Rescue Institute Full Video at the bottom So progressing up through the levels of mechanical advantage from 3:1, we can go to

Mechanical Advantage, Part 1
Thanks to Peak Rescue Institute Full Video at the bottom! In general, the Ideal Mechanical Advantage (IMA) is the ratio between the distance the load moves and

Haul System Basics & Pulley Systems on Rope
Thank you Peak Rescue Institute Let’s begin with manual hauls. When you talk about manual hauls or mechanical advantage, you have to talk about work.
