Page 6 - To reduce a mixed number to an improper fraction. RULE. Multiply the whole number by the denominator of the fraction, and to the product add the numerator for a new numerator, and place it over the denominator. 1. Reduce 127T^ to an improper fraction.
Page 154 - When no unguent is interposed, the friction of any two surfaces, whether of quiescence or of motion, is directly proportional to the force with which they are pressed perpendicularly together ; so that for any two given surfaces of contact there is a constant ratio of the friction to the perpendicular pressure of the one surface upon the other. Whilst this ratio is thus the same for the same surfaces of contact, it is different for different surfaces of contact. The particular value of it in respect...
Page 45 - To find the solidity of a sphere or globe. Rule.— Multiply the cube of the diameter, ce, by the decimal .5236.
Page 41 - Sphere is a body bounded by a uniformly curved surface, all the points of which are equally distant from a point within called the center.
Page 154 - When no unguent is interposed, the amount of the friction is, in every case, wholly independent of the extent of the surfaces of contact ; so that the force with which two surfaces are pressed together being the same, their friction is the same, whatever may be the extent of their surfaces of contact.
Page 38 - To find the solidity of a cube or right prism. Rule. — Multiply the area of the base by the perpendicular height, and the product will be the solid contents.
Page 11 - Having given the first term, the common difference, and the number of terms, to find the last term.
Page 10 - Find the greatest square number in the first or left hand period, place the root of it at the right hand of the given number, (after the manner of a quotient in division) for the first figure of the root, and...
Page 233 - ... per cent., and even less, in some kinds. Steel may be distinguished from iron by its fine grain; its susceptibility of hardening by immersing it, when hot, in cold water ; and with certainty by the action of diluted nitric acid, which leaves a black spot on steel, and on iron a spot which is lighter colored in proportion as the iron contains less carbon. There are many varieties of steel, the principal of which are : Natural steel, which is obtained by reducing the rich and pure kinds of iron...
Page 95 - The velocity given to find the space fallen through, to acquire that velocity. RULE. — Divide the velocity by 8, and the square of the quotient will be the distance fallen through to acquire that velocity.
