Containing Notes to the Rules and Examples of Part I.; Explanations of the Construction of Scales, Tables, and Diagrams, and a Treatise upon Equivalent Square Bases and Equivalent Level Heights. The whole illustrated by numerous original engravings, comprising explanatory cuts for Definitions and Problems, Stereometric Scales and Diagrams, and a series of Lithographic Drawings from Models : Showing all the Combinations of Solid...
Stranica 258 - ... unit less than the number of figures contained in the integer number. In this table, as is generally the case, the index to the logarithm of every number above 100 is omitted ; yet in the operation must be prefixed according to this remark; so...
Stranica 10 - ... paper, their areas calculated, and the solid contents of the excavations and embankments computed; generally by one of two rules, viz : No. 1 : By Arithmetical Average. — Multiply the sum of the end areas by their distance apart, and divide the product by 6 and by 9; the result will give, approximately, the number of cubic yards in the given length of excavation or embankment. No. 2 : By Geometrical Average. — Multiply the sum of the end areas, and the square root of their product, by the...
Stranica 4 - The areas of similar plane figures are proportional to the squares of their corresponding lines. Written Work 1. If a rectangle is 20 ft. by 50 ft., what will be the length of a similar rectangle 30 ft. in width ? 2. The side of a square field is 40 rods. Find the side of a similar field that contains four times as many acres. 3. A lady buys two rugs, one 6 ft. by 9 ft. and...
Stranica 72 - To find the surface of a cylinder. RULE. — Multiply the circumference of the base by the altitude, and to the product add the areas of the two ends ; the sum will be the whole surface. 1. What is the surface of a cylinder, whose length is 4 feet, and the circumference 3 feet ? Ans.
Stranica 10 - Average. — Multiply the sum of the end areas by their distance apart, and divide the product by 6 and by 9; the result will give, approximately, the number of cubic yards in the given length of excavation or embankment. No. 2 : By Geometrical Average. — Multiply the sum of the end areas, and the square root of their product, by the distance apart, and divide the product by 9 and by 9. The result will be, nearly, the number of cubic yards in the given length of excavation or embankment. Of these...
Stranica 11 - ... at gilding a pill, and no Miss Grace Goodchild is introduced whose character is formed by the process recommended, the essays are eminently readable, and the training which the author pleads for is practically illustrated, and made so clear as to give at every corner hints for every-day life. 4. — Field-Book for Railroad Engineers.
