Pàgina 568 - specific gravity of a body is the ratio of its weight to the weight of an equal volume of some other body assumed as a conventional standard. The standard usually adopted for solids and liquids is rain or distilled water at a common temperature. In bodies of equal magnitudes the specific gravities are directly as
Pàgina 733 - divisor by the last figure of the root, subtract the product from the dividend and to the remainder bring down the next period for a new dividend. Multiply the square of the
Pàgina 754 - parallel. A rectangle is a parallelogram whose angles are all right angles. A square is a rectangle whose sides are equal A pentagon has 5 sides and 5 angles ( A hexagon has 6 sides and 6 angles — A heptagon has 7 sides and 7 angles
Pàgina 756 - by drawing diagonals; find the areas of these, as above shown, for the area. To find the area of a regular polygon, multiply half the perimeter of the polygon by the perpendicular drawn from the centre to the centre of one of the sides. To find the area of a trapezoid, multiply half the sum of the parallel sides by the
Pàgina 776 - MEASURES OF WEIGHT. 10 milligrams (mg.) = 1 centigram, eg., 10 centigrams, 10 decigrams, 10 grams, 10 dekagrams, 10 hectograms, 10 kilograms, 10 myriagrams, 10 quintals, 1 decigram, dcg., 1 GRAM, gm., 1 dekagram, dkg., 1 hectogram, hg., 1
Pàgina 29 - Multiply the diameter of the driver by its number of revolutions, and divide the product by the number of revolutions of the driven pulley. The quotient will give the proper size of the driven pulley.
Pàgina 29 - of revolutions it should make, and divide the product by the revolutions of the driver. The quotient will be the required size of driver. Rule for finding the diameter of a driven pulley for a given number of revolutions, the diameter and revolutions of the driver
Pàgina 762 - times the diameter of the sphere subtract twice the height of the segment; multiply the difference by the square of the height, and by '5236. To find the cubic contents of a
Pàgina 762 - a cone, add together the areas of the two ends, and the mean proportional between them (that is, the square root of their product), and multiply the sum by one-third of the
Pàgina 9 - the action of the inclined plane by presenting, in effect, a continued series of planes. The screw, in principle, is that of an inclined plane wound round a cylinder, which generates a spiral of uniform inclination, each revolution producing a rise or traverse motion equal to the pitch of the screw — that is, the distance between
