Challenge Problems
Push your limits with challenges.
Question 1
A new machine component is designed with a yield stress of 400 MPa. During testing, it faces a bending stress of 350 MPa. Determine if the design is safe. Justify your answer using the Maximum Normal Stress Theory.
💡 Hint: Compare bending stress to yield stress.
Question 2
In a ductile material under torsion, if the yield shear strength is 150 MPa and max shear stress is calculated to be 200 MPa, identify the failure status and explain why based on the shear theory.
💡 Hint: Recall the relationship between shear stresses.
