This question is about material selection process for a solid eylindrical tension rod of diameter d and fixed length L. The rod is to be used in aerospace applications, where light weight, high strength, and high stiffness are all impo be subjected to a static axial force, F A safety factor of ng is desired. The materials can be more than one but you need to put your explanation and analysis for justification.
