Maths is important to mechanics and machinists. It can mean the difference between having a design fail or getting it right the first time. If you're rusty on your maths and need a good review, this is a great book to have.
Chapters include common fractions, decimal fractions, short methods, weights and measures, percentages, ratios and proportions, density and specific gravity, and powers and roots.
The geometry chapters cover plane surfaces, triangles, circles, graphical methods, prisms, cylinders, pyramids and cones, spheres, and other solids.
The algebra chapters include notation, formulas and translations, positive and negative numbers, addition and subtraction, exponents and powers, quadratic equations, variation, graphics, logarithms, angles, trig functions, trig tables, right triangle, and more.
You'll learn the maths in short, clearly explained lessons. Then you'll be asked to solve problems like "Two steam boilers of the same shape are respectively 12' and 15' long. Find the ratio of their surfaces". After you solve the problem, you can check it against the answers given.
Another problem asks "To what diameter should a piece of stock be turned so that it may be milled to a hexagon and be 1 3/4" across the flats?".
Or solve this one: "The pulley on the head stock of a lathe is 3" in diameter. This is belted to an 8" pulley on a shaft that makes 420 revolutions per minute. At what rate will a block of wood placed in the chuck revolve?". You'll be able to solve these and hundreds of other problems.
You get a big book loaded with valuable lessons and practical problems.
