posite shaft shown, composed of a steel (G = 77 GPa) core inside an aluminum (G = 25 GPa) jacket, carries a torque, T = 10 kN-m. The shaft is designed such that the aluminum jacket will fail first upon the application of the torque. What must be the minimum shear strength of steel such that the aluminum jacket will fail first? (Please explain)
