71Optic neuropathy — Classification and external resources ICD 10 H46 The optic nerve contains axons of nerve cells that emerge from the retina, leave the eye at the optic disc, and go to the visual cortex where input from the eye is processed into vision. There are… …
72Stress field — A stress field is a region in a body for which the stress is defined at every point. Stress fields are widely used in fluid dynamics and materials science.Intuitively, one can picture the stress fields as the stress created by adding an extra… …
73Burnishing (metalworking) — Burnishing is the plastic deformation of a surface due to sliding contact with another object. Visually, burnishing smears the texture of a rough surface and makes it shinier. Burnishing may occur on any sliding surface if the contact stress… …
74Strengthening mechanisms of materials — Methods have been devised to modify the yield strength, ductility, and toughness of both crystalline and amorphous materials. These strengthening mechanisms give engineers the ability to tailor the mechanical properties of materials to suit a… …
75Drill string — A drill string on a drilling rig is a column, or string, of drill pipe that transmits drilling fluid (via the mud pumps) and torque (via the kelly drive or top drive) to the drill bit. The term is loosely applied as the assembled collection of… …
76Truss — For other uses, see Truss (disambiguation). In architecture and structural engineering, a truss is a structure comprising one or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes.… …
77Flexural strength — Flexural strength, also known as modulus of rupture, bend strength, or fracture strength,[dubious – discuss] a mechanical parameter for brittle material, is defined as a material s ability to resist deformation under load. The transverse bending… …
78metallurgy — metallurgic, metallurgical, adj. metallurgically, adv. metallurgist /met l err jist/ or, esp. Brit., /meuh tal euhr jist/, n. /met l err jee/ or, esp. Brit., /meuh tal euhr jee/, n. 1. the technique or science of working or heating metals so as… …
79Concrete — This article is about the construction material. For other uses, see Concrete (disambiguation). Outer view of the Roman Pantheon, still the largest unreinforced solid concrete dome.[1] …
80Dyson sphere — A Dyson sphere (or shell as it appeared in the original paper) is a hypothetical megastructure originally described by Freeman Dyson. Such a sphere would be a system of orbiting solar power satellites meant to completely encompass a star and… …
