Q-1. You are testing a circular beam of two metals, 1045 steel and 2014-T6 aluminum, in a rotating-cantilever beam fatigue test. If you need to choose one of these metals so that you can essentially design a part made of that metal, and subject the part to a repetitive stress-amplitude without ever failing due to fatigue, which one would you choose. (See the attached figure) Q-2. What is the fatigue strength for the 1045 steel alloy, if you expect to...
