| A connection of two similar materials by a force which tends to shorten a member.
|
| The ability of a structural material to withstand compression forces; the measured maximum resistance of a concrete or mortar specimen to axial loading; expressed as force per unit cross-sectional area; or the specified resistance used in design calculations, in the U.S. customary units of measure expressed in pounds per square inch.
|
| One designed to stop the flow of water by the action of a flat washer closing against a seat.
|
| Abnormal wood formed on the lower side of branches and inclined trunks of softwood trees; compression wood shrinks excessively lengthwise, as compared with normal wood.
|
| 1. Force which tends to crush adjacent particles of a material together and cause overall shortening in the direction of its action; stress which tends to shorten a member. 2. The increase of pressure on a fluid by using mechanical energy.
|
| The measured resistance of a concrete or mortar specimen to axial loading expressed as pounds per square inch of cross-sectional area; the maximum compressive stress which material, such as portland cement, concrete, or grout is capable of sustaining.
|
| Volume, in cubic inches, represented by the area of the compressor piston head or heads multiplied by the length of the stroke.
|
| Leakproof seal between crankshaft and compressor body in open type compressors.
|
| See Compressor, Open Type.
|
| See Hermetic Compressor.
|
| Compressor having two or more compressive steps. Discharge from each step is the intake pressure of the next in series.
|
| Compressor in which the crankshaft extends through the crankcase and is driven by an outside motor; also called External Drive Compressor.
|
| See Reciprocating Compressor.
|
| Compressor which uses vanes, eccentric mechanisms or other rotating devices to provide pumping action.
|
| Compressor having only one compressive step between low-side pressure and high-side pressure.
|
| A machine that compresses gases or air; pump of a refrigerating mechanism which draws a low pressure on the cooling side of the refrigerant cycle and squeezes or compresses the gas into the high-pressure or condensing side of the cycle.
|
| Coaxial cable which transmits computer signals.
|
| Special flooring designed to prevent electrostatic buildup and sparking in a computer room; usually elevated above the existing floor, to facilitate the running of wires between the components in the room.
|
| All of the physical equipment, including the input units (keyboard and mouse), processing unit, and output units (screen, and printer).
|
| A code used to write a computer program.
|
| The programs that make a computer function.
|
| Arcane jargon used by computer technologists.
|
| An air-conditioning unit used in a computer room.
|
| A fillet weld having a concave face.
|
| In masonry, a mortar joint formed with a special tool or a bent iron rod; this joint is weather resistive and inexpensive.
|
| Curved or rounded inward like the inside of a bowl; the opposite of convex.
|
| The maximum distance from the face of a concave fillet weld perpendicular to a line joining the toes.
|
| A suspended ceiling framework that is completely hidden by the tiles or panels it supports.
|
| A recessed horizontal slot in a plaster wall, formed by a sheet metal screed, used to hang pictures and other objects.
|
| A hidden z-shaped bar that is used as a wall tie.
