Challenge Problems
Push your limits with challenges.
Question 1
A tensile test on a metal sample results in a yield stress of 250 MPa and an ultimate tensile strength of 400 MPa. If an application requires a safety factor of 2, what is the maximum allowable working stress for the material?
💡 Hint: Divide the yield strength by the safety factor to find the working stress.
Question 2
Why is it important for materials used in construction to have both high strength and good ductility? Provide an example.
💡 Hint: Consider how a failure would affect a structure's safety.
