Challenge Problems
Push your limits with advanced challenges
You have a hollow shaft with outer diameter 90 mm, inner diameter 70 mm, and it’s 3 m long. If a torque of 500 N·m is applied, find the angle of twist and shear stress.
💡 Hint: Make sure to consider the dimensions while calculating.
Given a hollow shaft designed for rigidity, how would you optimize the outer diameter for a specified shear stress if the inner diameter is fixed? Present calculations.
💡 Hint: Discuss material selection and dimensions effectively.
