Abstract
THE application of scientific discoveries to engineer ing practice generally only becomes possible when new technique and new materials have been developed which make possible the application. During the last century great advances have been made in engineering, and the success achieved has in no small measure been dependent upon the find ing of new materials, developments of accurate methods of testing the properties of materials under ordinary and high temperatures under static and repeated stresses, and how these properties are affected by heat treatments and manufacturing conditions. Further, the materials that are used in the largest quantities in modern engineering are irons and steels, which are subject to rapid corrosion in many atmospheric conditions, and thus where possible such metals, as well as the timbers, have to be protected by suitable coverings.
