C. of the key upon the initial stresses in the cross-head fit, andit is clear that the enlarged ends by bottoming in the fit havethe advantage of causing compression of the material at theend of the rod, as contrasted with the other form with theshoulder, in which the metal is stretched by the key in itsweakest spot. This tension invites fracture, and a bad featureof the stress is that it cannot be measured or even estimated. 10 AMERICAN ENGINEER AND RAILROAD JOURNAL.
