Σελίδα 304 - Every body continues in a state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by a force impressed upon it.
Σελίδα 207 - Find the value of one of the unknown quantities, in terms of the other and known quantities...
Σελίδα 296 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
Σελίδα 248 - A circle is a plane figure bounded by a curved line, called the circumference, every point of which is equally distant from a point within called the center.
Σελίδα 529 - Consider, for instance, joint 6, the polygon for which is a gij a. Notice that the corresponding letters AGIJA, on the truss, follow one another around the joint in such a manner that in passing from one to another we move in a direction opposite to that in which the hands of a clock move, and by naming them all we go around an entire circle in the same direction, passing from A to G, from G to /, from / to J, etc. This gives the directions of the corresponding lines in the diagram for the given...
Σελίδα 77 - In order to find the square root of a number, the first step is to find how many figures there will be in the root. This is done by pointing off the number into periods of two figures each, beginning at the rig/it.
Σελίδα 93 - The terms of a ratio are the two numbers to be compared ; thus, in the above ratio, 20 and 4 are the terms. When both terms are considered together, they are called a couplet ; when considered separately, the first term is called the antecedent, and the second term the consequent. Thus, in the ratio 20 : 4, 20 and 4 form a couplet, and 20 is the antecedent, and 4 the consequent.
Σελίδα 97 - The first and fourth terms of a proportion are called the extremes; and the second and third terms the means. Thus, in the proportion a : b = с : d, a and d are the extremes, and b and с the means.
Σελίδα 378 - ... the ratio of the ovendry weight of a sample to the weight of a volume of water equal to the volume of the sample at some specific moisture content, as green, air-dry, or ovendry.
Σελίδα 11 - The number thus added to itself, or the number to be multiplied, is called the multiplicand. The number which shows how many times the multiplicand is to be taken, or the number by which we multiply, is called the multiplier.
