(Environmental Engineering) (FSS) is the matter remaining from the suspended solids analysis which will not burn at 550°C. It represents the non-filterable inorganic residue in a sample.
(english) The intensity of internal force acting at a point in an object. Stress is measured in units of force per area. See shear stress and normal stress.
(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.
(Concrete Engineering) The maintenance of ambient conditions during the setting and hardening of concrete so that heat is neither lost nor gained from the surroundings of the concrete.
(english) Strain measuring the intensity of racking in the material. Shear strain is measured as the change in angle of the corners of a small square of material.
(Environmental Engineering) The suspension of particles by sufficient upward velocity of the fluid. During fluidization the gravity force is overcome by a combination of buoyancy and fluid friction.
(Concrete Engineering) A visible lineation which forms when the placement of concrete is delayed. The concrete in place hardens prior to the next placement of concrete against it.
(Concrete Engineering) A finely ground high density plaster composed of anhydrous, (calcined or "dead burned") gypsum, the set of which is accelerated by the addition of other materials.
(english) A valve that may be used to divert the flow of fluid in a passage. Most normally configured in a two-way pattern that is either open or closed.
(english) Tin Mill term; Thickness divided by .00011. Also weight in pounds of one Base Box of Tin plate. In finished inventory base weight is specified instead of decimal thickness.
(Software Engineering) a nondimension ratio (between 0 and 1) that provides an indication of the degree to which errors are removed from software before it is released to end-users
(english) A fabric or plastic device that is used with an o-ring or other gasket to prevent extrusion of the o-ring or gasket into an adjacent space or crevice
