soustend

Soustend is a term that can refer to several related concepts, primarily in the context of geometry and mechanics. In its most common usage, it denotes the angle subtended by an arc or a line segment at a particular point. For instance, an arc subtends an angle at the center of the circle and also at any point on the circumference. The magnitude of the subtended angle depends on the length of the arc and the distance from the point of observation.

The concept of subtending is also relevant in physics and engineering. A force or a load can be said to subtend a stress on a material. Similarly, in optics, a lens subtends an image of an object. The principle of subtending is fundamental to understanding spatial relationships and how objects or forces project onto other entities.

In simpler terms, something subtends another thing when it creates an angle or occupies a certain angular space relative to it. This is a core concept in trigonometry and is applied across various scientific disciplines to describe geometric relationships and angular measurements.
