In an engineering application, the material is a strip of iron with a fixed crystallographic structure subject to a tensile load during operation. The part
failed (yielded) during operation and needs to be replaced with a component with better properties. You are told that two other iron strips had failed
at yield stresses of 110 and 120 MPa, with grain sizes of 30 microns and 25 microns respectively. The current strip has a grain size of 20 microns. The
diameter of the rod is 1 mm and the load applied is 100 N. What is the yield stress of the new part C and would you recommend it for operation?
