Mechanical Advantage Theory

Mechanical Advantage is a measure of the force multiplication achieved by using a tool. In most cases, this involves using pulleys, but that isn’t always the case. The purpose is to show how we can achieve more work with less people AND that sometimes having more people can actually be dangerous. An overeager group of strapping young men and women on a given mechanical advantage system can yield an explosion of power, that when not desired, could actually create problems.

We’ll start the Mechanical Advantage Theory course by getting an overview of what mechanical advantage theory is and how progressions work to build advantage into a system sequentially. Now, the word “theory” should grab your attention; it’s a vacuum word, and we don’t work in vacuums. Life throws all kinds of stuff at us and systems are no different. So, we’re aiming at introducing you to the personality and characteristics of mechanical advantage systems. And yes, we’ll be covering much more in the advanced Technician section that follows.

Most systems in place are used during either raise or lower systems, so we’ll focus on these two areas. However, we all know that while these make up roughly 70%-80% of our mechanical advantage needs, there are other areas we want to make you aware of.

What You’ll Learn

We’ll cover, in-depth, things like horizontal systems and elevated system later, but we’ll touch briefly on these here to give you some circumspection. Other topics you’ll learn about include:

Haul system basics and pulley systems on rope

The framework for which how to determine mechanical advantage via the T-Method

Mechanical advantage progression from 3:1 to 9:1

Quick rules of thumb for fieldwork

Complex Systems where Mechanical Advantage systems are used

And more!
