Challenge Problems
Push your limits with challenges.
Question 1
A composite shaft composed of copper, aluminum, and steel has given lengths and moduli. Determine the maximum shear stress if an example torque is applied at one end.
💡 Hint: Remember to account for each sub-material's properties in your calculations.
Question 2
Design a composite shaft to optimize the load-bearing capabilities given constraints on weight and torsional rigidity. Provide calculations supporting your design.
💡 Hint: Consider ratios of material stiffness and shaft dimensions to achieve balance.
