Σελίδα 36 - From half the sum of the three sides subtract each side separately. Multiply the half sum and the three remainders together ; the square root of the product is the area.
Σελίδα 40 - Case 1. — When the fulcrum of the lever is between the power and the weight. RULE. — Divide the weight to be raised by the power to be applied ; the quotient will give the difference of leverage necessary to support the weight in equilibrio. Hence, a small addition either of leverage or weight will cause the power to preponderate. EXAMPLE 1. — A ball weighing 3 tons, is to be raised by 4 men, who can exert a force of 12 cwt.: required the proportionate length of lever ? 60 3 tons = 60 cwt.;...
Σελίδα 27 - Of four-sided figures, a square is that which has all its sides equal, and all its angles right angles.
Σελίδα 11 - Pyramid, RULE. — Multiply the sum of the perimeters of the two ends by the slant height, and...
Σελίδα 12 - To find the solidity of a wedge. RULE. To the length of the edge add twice the length of the base ; multiply that sum by the height, and by the breadth of the base, and one-sixth of the product will be the solidity.
Σελίδα 152 - Is that point into which, if the whole mass were collected, a given force, applied at a given distance, would produce the same angular velocity in the same time as if the bodies were disposed at their respective distances. This point differs from the Centre of Oscillation only in this, that, in the latter case, the motion is produced by the gravity of | the body; but, in the former, the body is put in motion by some | other force, acting at one place only.
Σελίδα 32 - NOTE. — 1. As 7 is to 22, so is the diameter to the circumference; or, as 22 is to 7, so is the circumference to the diameter.
Σελίδα 69 - Take two ounces of tripoli powdered, put it into an earthen pot, with just enough water to cover it ; then take a piece of white flannel, lay it over a piece of cork or rubber, and proceed to polish the varnish, always wetting it with the tripoli and water.

Σελίδα 16 - ... being decimally reckoned, advance tenfold from the commencement to the termination of each radius : thus, suppose 1 at the joint be one, the 1 in the middle of the rule is ten, and 1 at the end one hundred : again, suppose 1 at the joint ten, 1 in the middle is 100, and 1 or 10 at the end is 1000, &c., the intermediate divisions on which complete the whole system of its notation. TO MULTIPLY NUMBERS BY THE RULE. Set 1 on B opposite to the multiplier on A; and against the number to be multiplied...
