The frame of a space shuttle type vehicle must have a high yield strength, high stiffness, and the most important design factor is weight. Of all the materials presented in this chapter, what material might be the most suitable for the frame of a space shuttle. Assume that there will be both tensile and compressive stresses. For a space shuttle cost is not a limiting factor. (a) You can eliminate entire classes of materials from consideration with a brief statement about their unsuitability
