A unit of weight equal to 16 ounces (7,000 grains) avoirdupois or 12 ounces (5,760 grains) troy. Abbreviation is lbs.
Measure of the load pressure of one commodity on another. Atmospheric pressure at sea level is 14.696 psi with Fluid pressure (liquid & gas) being measured in terms of pounds per square inch absolute or pounds per square inch gauge.
Measurement of pressure as measured on a pressure gauge with the addition of atmospheric pressure, which is 14.696 at sea level, therefore, a pressure of 30 pounds per square inch gauge (psig) is equal to 44.696 pounds per square inch absolute (psia).
Fluid pressure (liquid and gas) as measured on a pressure gauge without the inclusion of atmospheric pressure.
Concrete wall that is poured into forms and set-up in the place where it will remain.
Concrete or mortar that is poured and cured in the place where it will remain permanently, such as concrete slab foundations.
This "loose" insulation is poured into open spaces in a house, possibly an attic floor. Cellulose and Fiberglass are two types of this insulation, which comes in bags that are opened and poured into place and leveled or raked with a board.
Application of a melted powder metal coating by use of a spray method. When hard surface metals, which are brittle when used alone, are sprayed onto a softer metal, they provide a hard and wear-resistant surface.
The deterioration, over a period of time, of varnish into dust, when it is exposed to unsuitable conditions.
1. Great ability to do, act or affect.
2. Electrical circuit ability in watts with a watt being equal to the voltage multiplied by current.
3. The capacity to exert physical force or energy.
Multiple conductor electrical cable, which can be, used for electrical applications such as machines and tools.
Cart with a wheelbarrow type bin, with a rocker attachment allowing steep dumping for stiff mixes, which transports wet concrete over a job site. These carts can be either diesel or gasoline powered and vary in size with the ability to carry from nine to twelve cubic feet of concrete.
A shopping center with few tenants, most of them anchor tenants. Generally, a power center's anchor tenants are "category killers", that is, the dominant retailer in the market they serve.
Electrical efficiency shown as a ratio of the true electrical power, which is the amount that remains after reduction by losses in the circuit. To correctly gauge the circuit needed to for the intended electrical load, the value must be multiplied by the power factor.
Device with flat blades which are tilted at a slightly horizontal angle and are fastened to the end of a rotating hub, used to compact wet concrete. The electric or gasoline motor turns the hub and blades so that they cross the surface of the uncured concrete, compacting it.
Gun shaped hammer, which is used, for driving fasteners into concrete in places where a nail gun does not have sufficient power. The explosive force of the blank cartridges, which drive this hammer, are powered by igniting the powder in the cartridge, which has to be changed for each fastener.
Document authorizing an individual to act on behalf of someone else.
A provision in a mortgage agreement that grants the lender (or trustee) the right to sell the property upon certain default. The property is to be sold at auction but court authority is unnecessary.
Combination of a miter box with a powered circular saw that is mounted on a table, using a hinge so that it can be set to cut at angles from 45 to 90 degrees, making a portable substitute for a radial arm saw and is used to cut trim and molding on site.
Power driven, portable plane that smoothes and whittles away at the size of a piece of wood.
Electricity generating plant.
Powered winch that pulls electrical cable through long runs of conduit.
Hand-held, electric or air-powered ratchet which is used to drive a socket to turn bolts or nuts.
Drawing which indicates the service entrance components of an electrical circuit that is used as a reference for installing wiring and service entrance components.
Electrically or compressed air driven saws such as circular saws, table saw, saber saws, radial arm saws, etc.
Motor powered rigid, straight piece of metal or wood which is used to level concrete after it is poured. The two screed boards are attached to the frame where the motor is mounted and the screed boards are moved back and forth across the concrete.
Screwdriver, either electrically powered or cordless (battery powered) with interchangeable bits which may be used to drive fasteners into wallboard or panels or to drill holes with the drill bits.
Electric or gasoline powered trowel with revolving blades used to smooth and finish wet concrete.
