Hi, I'm struggling with this question on an exam pastpaper. I have attached the question and worked solutions below and i am stuck on Q10 c). I'm not sure how they knew that the torque is constant along the whole shaft. I thought a stepped shaft has different torques for its different sections since the length & cross sectional area of the sections are different. Can someone please explain this to me, thank you(adsbygoogle = window.adsbygoogle || []).push({});
