(english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different.
แรงกระทำเทียบเท่าที่จุดต่อ
(Environmental Engineering) The removal of divalent cations by precipitation or ion exchange.
(english) A system of forces which is statically equivalent to a stress distribution over an area.
(english) Having the equivalent lattice points at the corners of the unit cell, and at its center; sometimes called centered, or space-centered.
(Environmental Engineering) A bond in which electrons are shared approximately equally by two atoms.
(english) An alloy that is 70% copper,30% zinc. One of the most widely used of the copper-zinc alloys; malleable and ductile; excellent cold-working but poor hot-working and machining properties; excellent for soft-soldering; good for silver alloy brazing or oxyacetylene welding, but fair for resistance or carbon-arc welding. Used for drawn cartridges, tubes, eyelets machine items and snap fasteners.
(english) The resultant of a system of forces is a single force or moment whose magnitude, direction, and location make it statically equivalent to the system of forces.
(english) Pressure is a similar idea to stress, the force intensity at a point, except that pressure means something acting on the surface of an object rather than within the material of the object. When discussing the pressure within a fluid, the meaning is equivalent to stress.
ปูนซีเมนต์กันน้ำ
(english) A system of forces composed of two equal forces of opposite direction, offset by a distance. A couple is statically equivalent to a moment whose magnitude equals the magnitude of the force times the offset distance.
