Question 1
When does the Maximum Normal Stress Theory predict failure?
- When maximum stress is less than yield strength
- When maximum principal stress exceeds yield stress
- When shear stress is maximum
💡 Hint: Think about what provides the limits for brittle materials.
Question 2
True or False: The Factor of Safety only considers the yield strength of a material.
- True
- False
💡 Hint: Remember the definition of FoS.

Challenge Problems
Push your limits with challenges.
Question 1
A crankshaft experiences cyclic loads from an engine. Use the Goodman criterion to determine if a material is suitable based on given loads and endurance limits.
💡 Hint: Work through the stress calculations carefully.
Question 2
Design a structural beam using all three static theories. Justify which failure theory is optimal for its application, considering material properties and loading conditions.
💡 Hint: Think critically about how each theory applies to real-world stresses.
