tailieunhanh - A Handbook for the Mechanical Designer Second Edition

An engine or motor is a machine designed to convert energy into useful mechanical motion.[1][2] Heat engines, including internal combustion engines and external combustion engines (such as steam engines) burn a fuel to create heat which is then used to create motion. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others, such as clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors like myosins in muscles use chemical energy to create motion | ENGINEERING COOKBOOK A Handbook for the Mechanical Designer Second Edition Copyright 1999 This handy engineering information guide is a token of Loren Cook Company s appreciation to the many fine mechanical designers in our industry.
