(Environmental Engineering) Organic compounds with two hydrocarbon groups bonded to a carbonyl group.
(english) In two dimensions, a pin support restrains two translation degrees of freedom but does not restrain rotation. When considering reaction forces, a pin support is usually considered to have two force components: one each about the x and y axes respectively.
(Environmental Engineering) A bond in which electrons are shared approximately equally by two atoms.
(english) Joining two edges or ends by placing one against the other and welding them.
(english) In two dimensions, a pin connection restrains two translation degrees of freedom but does not restrain rotation. Since the rotation degree of freedom is unrestrained at a pin connection, it transfers no moment.
(Environmental Engineering) Two or more different compounds with the same chemical formula but different structure and characteristics.
(Environmental Engineering) Water which is contained in geologic strata. Also properly written as two words, ground water.
(english) In two dimensions, a fixed connection between two members restrains all three degrees of freedom of the connected member with respect to one another. A fixed connection is sometimes called a rigid connection or moment-resisting connection.
(Environmental Engineering) Any organic compound composed entirely of carbon and hydrogen. Two examples are methane gas and octane.
(english) 1) Roll used as a support roll mainly for plater rolls. 2) Two rolls, one on top and one on bottom of the two work rolls which apply pressure and reduce the flexing of the work rolls.
(english) A separator or diaphragm usually found in a chamber to facilitate separation of two (2) fluids or gases.
(english) A coil made by putting together two or more coils to make one max coil or one shippable coil.
