Abstract : The point of the memorandum is to emphasize the danger in accepting engineering data at face value. The definition of units used in the measurement of engineering parameters related to solid materials is discussed. A major portion of the memorandum is concerned with micromechanical strength parameters in solids such as yield strength, elastic limit, and proportional limit. Variation of elastic 'constants' in ordinary engineering materials under various conditions is discussed. A final section of the memorandum discusses variation of the thermal expansion coefficient in materials. (Author)
