A common automotive steel has a yield strength of 250 MPa when it is processed to have an average grain diameter of 2.5x10 mm. When the average grain diameter is decreased to 5x10 mm, the yield strength increases to 325 MPa. What is the average grain diameter (mm) when a yield strength of 375 MPa is require
