Page 5 - Scale: 4 farthings (far.) = 1 penny (d.); 12 pence = 1 shilling (s.) ; 20 shillings — 1 pound (£). 156.
Page 39 - The foot-pound is called the unit of work, and may be defined as the work done by a force of one pound acting through a distance of one foot.
Page 127 - Finish. — The wire shall be cylindrical in form and free from scales, inequalities, flaws, splints, and other imperfections. The finish of the wire shall be in accordance with the best commercial practice. Each coil shall be warranted not to contain any weld, joint, or splice in the rod before drawn.
Page 39 - ... substitute dyne for force as one factor, and cm. for space as the other factor in the equation w equals/ x s. Thus the equation reads, w equals dynes times cms. When so expressed, a new unit is conceived and is called an er'g. Thus the unit of work in the absolute system is called an erg, and is defined as the work done by a force of one dyne working through a distance of one cm. e = dxcm. If gms. of force is unit given instead of dynes, and ergs are desired this equation would apply: e equals...
Page 39 - British thermal unit (Btu) = l/180partof the heat required to raise the temperature of one pound of water from 32° F.
Page 39 - When a force acts on a body and motion takes place in the direction of the force, the force is said to do work.
Page 7 - ... fundamental unit of the metric system, and all units of length and capacity were to be derived directly from the meter which was intended to be equal to one ten-millionth of the earth's quadrant. Furthermore, it was originally planned that the unit of mass, the kilogram, should be identical with the mass of a cubic decimeter of water at its maximum density. At present, however, the units of length and mass are defined independently of these conceptions.
