Tension in a string is a non-negative vector quantity. Zero tension is slack. A string or rope is often idealized as one dimension, having length but being massless with zero cross section. If there are no bends in the string, as occur with vibrations or pulleys, then tension is a constant along the string, equal to the … See more In physics, tension is described as the pulling force transmitted axially by the means of a string, a rope, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object; tension … See more Tension is also used to describe the force exerted by the ends of a three-dimensional, continuous material such as a rod or truss member. In this context, tension is analogous to negative pressure. A rod under tension elongates.

What is the SI unit of surface tension? - Quora
WebAug 7, 2024 · The force per unit length perpendicular to a line drawn in the surface of the liquid is the surface tension. Its SI unit is newtons per metre, and its CGS unit is dynes per centimetre. The dimensions are MT −2. I have seen various symbols, such as T, S and γ used for surface tension. The first two of these symbols are already heavily worked ... WebLearn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.
