The yield strength for an alloy that has an average grain diameter of 4.6 x 10-2 mm is 141 MPa. At a grain diameter of 6.1 x 10-3 mm, the yield strength increases to 239 MPa. At what grain diameter, in mm, will the yield strength be 245 MPa?

Write a technical essay (maximum two pages) about stress concentration. and paste from the textbook. instead, read updated material about this phenomenon and provide a technical evaluation of the different techniques to avoid/reduce such phenomenon. consider in your analysis cutting-edge computational techniques such as fea to study and analyze stress concentrations.
