Excerpt from A Treatise on Friction and Lost Work: In Machinery and MillworkThe following pages contain the results of an attempt to exhibit the facts and laws involved in the waste Of energy by friction in machinery and mill-work. It is readily seen that in all well-designed machinery friction is the sole cause Of lost work. The other possible cause, the permanent deformation of parts, cannot in such cases exist: every piece which is altered in shape by the forces received and transmitted, since it is never sprung beyond the elastic limit, restores by its restoration Of form all energy expended in its alteration. Hence, the study Of the methods and magnitudes of friction losses, and the laws governing their production, is, next to the theory of pure mechanism, the most important study in rela tion to the transmission Of energy by machinery.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
