Challenge Problems
Push your limits with challenges.
Question 1
A cylindrical rod with a length of 2m and a varying radius experiences a torque of 100Nm at one end. Calculate the angle of rotation at the free end, assuming the radius varies linearly from 0.1m to 0.05m.
💡 Hint: Break the problem down into manageable parts: analyze the varying radius and find J accordingly.
Question 2
Given a composite shaft under torque with sections of different materials, how would you evaluate the overall twist experienced by the shaft?
💡 Hint: Remember to account for clamping at both ends, leading to zero overall rotation.
