Challenge Problems
Push your limits with challenges.
Question 1
Calculate the total twist in a cylindrical shaft of varying radius 1 cm at one end and 3 cm at the other, under a torque of 50 Nm over a length of 2 m.
💡 Hint: Consider how the varying radius impacts the polar moment of inertia.
Question 2
If a composite shaft consists of a bronze section with G = 40 GPa, an aluminum with G = 70 GPa, and a steel section with G = 210 GPa, how will the varying shear moduli affect the overall twist?
💡 Hint: Break down each material's twist contribution before summing them up.
