Challenge Problems
Push your limits with challenges.
Question 1
A solid circular shaft of radius 0.05 m experiences torque of 1000 Nm. Calculate the maximum shear stress and angle of twist if the shaft is 2 m long and made of steel with a shear modulus of 80 GPa.
💡 Hint: Break down the components: calculate J, shear stress, and then angle of twist.
Question 2
Design a hollow shaft for transmission that withstands a torque of 600 Nm. The available materials are aluminum (G=26 GPa) and steel (G=80 GPa). Determine the outer diameter if the inner diameter is 0.03 m.
💡 Hint: Consider the trade-offs between strength and weight to determine the optimal diameter.
