Challenge Problems
Push your limits with advanced challenges
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.
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.
