Hook-and-loop fastener spread evenly, as it is with rigid pieces. Three ways to maximize the strength of a bond between the two flexible pieces are: Shoe closures can resist a large force with only a small amount of hook-and-loop fasteners. This is because the strap is wrapped through a slot, halving the force on the bond by acting as a pulley system (thus gaining a mechanical advantage), and further absorbing some of the force in friction around the tight bend. This layout also ensures that the force is parallel to the strips. Touch fasteners are easy to use, safe, and maintenance free.
Wire rope sheave and rope diameters. A general dimensioning method of rope drives (and used besides the technical regulations) calculate the five limits The calculation of the rope drive limits depends on: The wire ropes are stressed by fluctuating forces, by wear, by corrosion and in seldom cases by extreme forces. The rope life is finite and the safety is only ensured by inspection for the detection of wire breaks on a reference rope length, of cross-section loss, as well as other failures so that the wire rope can be replaced before a dangerous situation occurs. Installations should be designed to facilitate
