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).
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.
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.
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.
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.
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.
