lication requires ultimate tensile strength and yield strength of a steel at 110 ksi and 91 ksi, respectively. 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?

4.1. Can SAE 1040 steel be selected for this application?
Ans :Yes, SAE 1040 steel can 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?
Ans: Yes,
SAE 1040 steel , Condition: WQT 700
ultimate tensile strength =127 ksi
and yield strength= 93 ksi
