Abstract
The Strength of Materials comprises not only mechanics of solids, which are not limited to elastic deformation, but also materials testing. Because the students who belong to the author's department have little knowledge about the materials' characteristics, they imagine that this subject is difficult. In this paper, it is discussed how to make the students understand the essential and some important points of this subject. For students in college of technology, the author points out that the lecture concentrating on the elastic deformation of solid members is most important and that the basic mathematics used in this subject must be explained once again early in this lesson.
