Members: Pendulum Physics
Pendulums present an interesting study of physics for rope technicians. A simple pendulum is made up of a point mass suspended by a string or rod of negligible mass. In rope systems, the the mass of the swinging

Two Point Anchor Loads
Most people understand that a load can be shared by two points. If the two anchors are directly above the load and equalised, they each feel half the load. Many people also know that if the two
Forces and Vectors
Understanding the concept of ‘force’ is key to working with ropes. This article explores this concept and how it may be quantified. Force The term ‘force’ describes the interaction between two objects. It is a vector quantity

Members: Redirection Forces
This article goes beyond the standard rule-of-thumb “90° puts 141% on the redirect anchor”. If we have a suspended load with a 90º redirection through an aluminium carabiner then we can calculate the effects of friction through
