Σελίδα 38 - RULE. To the sum of the areas of the two ends add the square root of their product ; multiply this sum by the perpendicular height, and \ of the product is the solid content.
Σελίδα 27 - Of four-sided figures, a square is that which has all its sides equal, and all its angles right angles.
Σελίδα 139 - Multiply the sectional area of the bottom flange in inches by the depth of the beam in inches, and divide the product by the distance between the supports also in inches; and 514 times the quotient equal the absolute strength of the beam in cwts. The strongest form in which any given quantity of matter can be disposed is that of a hollow cylinder; and it has been demonstrated that the maximum of strength is obtained in cast iron when the thickness of the annulus or ring amounts to...
Σελίδα 65 - RULE. — Divide the weight to be raised by twice the number of pulleys in the lower block ; the quotient will give the power necessary to raise the weight. EXAMPLE. — What power is required to raise 600 Ibs., when the lower block contains six pulleys ? 600 6 x 2 = 50 Iks., Ans.
Σελίδα 141 - Flexure by vertical Pressure. When a piece of timber is employed as a column or support, its tendency to yielding by compression is different according to the proportion between its length and area of its cross section ; and supposing the form that of a cylinder whose length is less- than seven or eight times its diameter, it is impossible to bend it by any force applied longitudinally, as it will be destroyed by splitting before that bending can take place; but when the length exceeds this, the...
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 33 - The areas of circles are to each other as the squares of their diameters, or of their radii.
Σελίδα 39 - To find the solidity of a spheroid. RULE. Multiply the square of the revolving axis by the fixed axis, and by *5236, and the product will be the solidity.
Σελίδα 93 - Take 2 ounces of tripoli powdered, put it in an earthen pot, with 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. It will be known when the process is finished by wiping a part of the work with a sponge, and observing whether there is a fair even gloss. When this is the case, take a bit of mutton suet and fine flour, and clean the work.
Σελίδα 29 - The side of a square is equal to the square root of half the square of its diagonal.
