This complete guide, originally pubilshed in 1908, presents the origins and mechanical principals of farm motors. Beginning with a brief and fascination introduction to "the animal as motor," Farm Motors by Davidson and Chase goes on to present an accessible and fully illustrated tutorial on energy and its sources, the law of transformation of energy, prime movers (such as heat engines) versus electrical motors, and much more. Also included are clear explanations of the mechanics of the most popular types of farm motors-including waterwheels, tidal machines, and windmills; steam engines; internal-combustion engines; traction engines; and current electricity-along with information on their construction. 3.5"x6", 222 pages.
