Answer the following 4 questions: 4.1. Can SAE 1040 steel be selected for this application? 4.2. If "no" is the answer in Part I, the following Part II, III, and IV can be ignored. If "yes" is the answer in Part I, which condition of SAE 1040 should be selected? 4.3. Why is that steel with the condition in part II selected? 4.4. Is the selected steel brittle or ductile? and Why? Page 4 of 6
