Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. [4] It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, drywall and blackboard or sidewalk chalk.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
(E.g. 1 mm diameter wire is ≈18 AWG, 2 mm diameter wire is ≈12 AWG, and 4 mm diameter wire is ≈6 AWG.) This quadruples the cross-sectional area and conductance. A decrease of ten gauge numbers (E.g. from 24 AWG to 14 AWG) multiplies the area, weight, and conductance by approximately 10.
Chiffon—6 to 8 mm (can be made in double thickness, i.e. 12 to 16 mm) Crepe de Chine—12 to 16 mm; Gauze—3 to 5 mm; Raw silk—35 to 40 mm (heavier silks appear more "wooly") Organza—4 to 6 mm; Charmeuse—12 to 30 mm; The higher the weight in mommes, the more durable the weave and the more suitable it is for heavy-duty use.
The weight stack on a selectorized cable machine; in this example, each plate weighs 6 kg. Weight machines commonly use specialized sets of plates (called "weight stacks"), consisting of a set of rectangular plates mounted on rails. Through a cable and pulley system, the burden is transferred to the machine's user.
So a 1 / 2 in (12.7 mm) diameter drill will be able to drill a hole 4 + 1 / 2 in (114.3 mm) deep, since it is 9 times the diameter in length. A 1 / 8 in (3.175 mm) diameter drill can drill a hole 1 + 5 / 8 in (41.275 mm) deep, since it is 13 times the diameter in flute length. [3]
