This also applies to cable, chain, and webbing.
Gear that is anchored includes anchors, rocks, trees, tripods, trucks, etc.
A "bight" is a simple loop in a rope that does not cross itself.
A "bend" is a knot that joins two ropes together. Bends can only be attached to the end of a rope.
A "hitch" is a type of knot that must be tied around another object.
"Descending devices" (e.g., ATCs, Brake Bar Racks, Figure 8s, Rescue 8s, etc) create friction as their primary purpose. The friction in descending devices is always considered when calculating forces.
The "Safety Factor" is the ratio between the gear's breaking strength and the maximum load applied to the gear (e.g., 5:1).
A Prusik is a progressive capture hitch (i.e., a ratchet). When overloaded, a Prusik should allow the rope to slip.
The gear connection point for vRigger's Prusiks is at the end of the loop. To connect a Prusik to another item, drag the Prusik until the blue connection dots overlap and then drop it.
vRigger includes several different Prusiks. When calculating forces, it is better to use a "double" Prusik (i.e., one piece of gear that contains two Prusiks) rather than two single Prusiks (e.g., a long and a short Prusik).
Adjustable Prusik
The knot named "Prusik (hitch, adjusts)" allows you to create a Prusik hitch of any length. A sample file explains how to use this adjustable Prusik hitch. There is also a snippet named "Prusik (hitch, adjusts)" that creates an adjustable Prusik hitch.
The "Pulley (w/Prusik)" includes two built-in Prusiks. This is a convenient method of placing tandem Prusiks next to a pulley.
