Excerpt from Balancing of Engines, Steam, Gas, and Petrol: An Elementary Text-Book, Using Principally Graphical Methods; For the Use of Students, Draughtsmen, Designers, and Buyers of Engines; With Numerous Tables and Diagrams The development of the motor-car engine, and the successful installation of steam turbines for land and marine use, have been the means of directing more attention to the subject of engine balancing. The smooth running of an engine depends mainly on two factors: a more or less uniform torque on the crank-shaft, and good balance of the inertia forces of the engine. The latter forms the subject-matter of the present work; the former cannot be left without any mention, a chapter is therefore devoted to it. With the exception of a few analytical investigations, the method of treatment is graphical. In fact, the engineering student will recognize many geometrical methods with which he is familiar as applied to Statics of Structures.
