Richard Delaney has worked professionally with ropes since 1992. Initially, this was as a multi-pitch, rock-climbing guide, but this soon morphed into specialized rescue instruction and rope access work. He is currently an accredited Vertical Rescue Instructor/Assessor, a Level 3 Rope Access Technician, a Technical Director of the Australian Rope Access Association, and the administrator of the Rope Test Lab group on Facebook. Understanding and teaching the Physics of Rigging is a core passion of Richard's, one based on his experience, and his prior professional life as a qualified engineer.

Clarke “Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to …

Types of Bearings:- The equipment in the industries is made of small-small parts. These parts are assembled to make full of working equipment.
Here we have a 3:1 mechanical advantage. First one end of the rope is attached directly to the load, this is then passed around an…
This presentation provides students with an introduction to the concepts of work, power, actual mechanical advantage, ideal mechanical advantage, efficiency, and the six simple machines. It is suitable for students in 7th, 8th, and 9th grade physical science classes. ...
A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in tandem are called a transmission and can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a non-rotating toothed part, called a rack, thereby producing translation instead of rotation.
