Ihispoint varies with the different crank pins,as the strain may be more on the main pinat one time than the others, and morewhen backing up than when going ahead,more on one quarter than on the oppositeone. {84) J. R. A., Dubuque, Iowa, writes:We have a discussion about the centerof gravity of one of our ten-wheel en-gines. The drivers are equally spacedfrom center to center, and the distancefrom center of main driver to center oftruck is II feet 6 inches. The weight ontruck is pounds; on drivers. RICHMOND CONSOLIDATION FOR RIO GRANDE WESTERN (sEE PAGE 395). tional resistance which fluids have to meetwhen flowing over or past stationary sur-faces, like the inside of a pipe or the bot-tom of a passage or river. The particlesor molecules of which a fluid is composedalso have some little friction when movedamong themselves; this friction is soslight that in actual practice it is not takeninto account. (80) J. B., Omaha, Neb., asks:Can steam get into cylinders with re-verse lever in the center notch? A.—Thatdepends on the way the link motion andvalves are designed; also on the way theeccentrics are set. If the eccentrics areset with very much lead the steam portwill be open in any position when thatside is on the center. If the valves arebuilt without much lap it is a hard matter rod strap, why doesnt piston knock cylin-der head out? A.—When running at ahigh speed there is considerable co
