Seller's Description:
1907. Longmans, Green. Hard Cover. Book-Good, black titles on front board & spine, brown boards, spine discoloured. 8.5x5.5. 212pp. Many b/w illus. At the beginning of the twentieth century, the smooth running of an engine depended 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 this volume.
