Nylon 66 can also be produced at laboratory scale in this way. Representative procedures and equipment lists for conducting the nylon rope trick demonstration are available in literature procedures. [2] The nylon rope trick was developed as a scientific demonstration by American chemist Stephanie Kwolek, who later invented Kevlar aramid. [3]
This was typically cut down to an 8-foot (2.4 m) length and a 18-inch (460 mm) web loop (wrist strap) attached near the top end. This was used to form a sling loop and attached to an over 100-foot (30 m) length of 5/8-inch nylon rope. Three ropes with McGuire Rigs attached could be dropped from a UH-1 "Huey" helicopter, all on the same side. A ...
The most popular webbing width is 25 mm (1 in) [2] but 38 mm (1.5 in) and 50 mm (2 in) are also very common. Narrower webbing is frequently looped through chock stones, which are jammed into cracks as safety anchors. In other cases, webbing is looped over rock outcroppings. Webbing is less likely to loosen itself off the rock than tubular rope.
A test of "single" standard rope involves tying an 80 kg (176 pound) weight to the end of a length of rope. This weight is then dropped 5 meters (16½ feet) on 2.7 meters (9 feet) of rope, with the rope running over a rounded surface simulating that of a standard carabiner. This process is repeated until the rope breaks.
Parachute cord (also paracord or 550 cord when referring to type-III paracord) is a lightweight nylon kernmantle rope originally used in the suspension lines of parachutes. This cord is now used as a general purpose utility cord. This versatile cord was used by astronauts during the 82nd Space Shuttle mission to repair the Hubble Space ...
Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural or synthetic fibres. [1] [2] [3] Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be ...
