Question 1
A brittle material has a yield strength of 250 MPa. If a load is applied causing a maximum principal stress of 225 MPa, will the material fail? Explain your reasoning.
π‘ Hint: Compare the applied stress with the yield strength.
Question 2
A designer is creating a shaft that will be made from a brittle material with a yield strength of 400 MPa. They anticipate a maximum normal stress of 450 MPa during operation. What must the designer consider to prevent failure?
π‘ Hint: Think about the implications of exceeding yield strength.
