Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of compression. Tension might also be described as the action-reaction pair of forces acting at each end of an object.
The rope is on the verge of full sliding, i.e. is the maximum load that one can hold. Smaller loads can be held as well, resulting in a smaller effective contact angle φ {\displaystyle \varphi } . It is important that the line is not rigid, in which case significant force would be lost in the bending of the line tightly around the cylinder.
The liquid rope coil effect or liquid rope coiling is a fluid mechanics phenomenon characterized by the steadily rotating helical structure formed when pouring a thin stream of viscous fluid from a sufficient height onto a surface, resulting from a buckling instability in which the initially vertical fluid stream becomes unstable to bending deformation under axial compressive stress.
Rope trick effects visible from one of Operation Tumbler–Snapper's tower-mounted test shots in 1952, taken with a rapatronic camera. The adjacent photograph shows two unusual phenomena: bright spikes projecting from the bottom of the fireball, and the peculiar mottling of the expanding fireball surface.
In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.
The standard model of a cosmic string is a geometrical structure with an angle deficit, which thus is in tension and hence has positive mass. In 1995, Visser et al. proposed that cosmic strings could theoretically also exist with angle excesses, and thus negative tension and hence negative mass .
It might be worth mentioning in the article the 5 vertical white lines visible in the lower right corner of the picture are not an example of the rope trick effect. Smoke devices were ignited prior to the detonation of the nuclear device to better facilitate the measuring and charting the expansion and effect of the primary nuclear device.--
With a traverse-rope fixed between two anchor points — ideally under some tension — the climber attaches to the rope using a short quickdraw (or equivalent alternative) that is attached to their harness. A backup attachment loop using carabiners and slings is also recommended. Any backpacks are separately clipped to the rope and also ...
