Challenge Problems
Push your limits with challenges.
Question 1
A steel shaft with a diameter of 0.05 m and length of 2 m has a shear modulus of 80 GPa. If a torque of 150 Nm is applied, calculate the angle of twist and discuss how changing the diameter affects the outcome.
π‘ Hint: Remember to deal with unit conversions if necessary.
Question 2
Design a system with a hollow shaft that connects two gears. If the outer diameter is 0.1 m and the inner diameter is 0.06 m with a length of 1.5 m, how would you determine the required torque if the desired angle of twist is limited to 0.02 radians?
π‘ Hint: Start by finding J for the hollow shaft.
