As we continue to apply more pulleys to the system then the mechanical advantage ratio increases. In this system some of the pulleys that have been used are double pulleys.
A double pulley has two pulley wheels usually of the same diameter housed inside a single block, the two pulley wheels are able to move independently of each other. By using a double or multiple pulley block we are able to condense the pulley system making it more manageable.
Angular vector forces occur when ropes are passed through a deviation or a directional pulley. Dependent on the angle created, this can have a multiplying…
Vector forces become apparent whenever there is an internal angle greater than 0° between two or more rigging components or anchorage points. For ease of…
A fall factor is a simple representation of the severity of a fall. It can be used to evaluate the potential loadings exerted on the…
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…
Pulley systems are used to provide us with a mechanical advantage, where the amount of input effort is multiplied to exert greater forces on a…
