A bar is subjected to a combination of a steady load of 60kN and a load fluctuating between - 10kN and 90 kN. The corrected endurance limit of the bar is 150 MPa, the yield strength of the material is 480 MPa and the ultimate strength of the material is 600MPa. The bar cross-section is square with side a. If the factor of safety is 2, the value of a (in mm), according to the modified Goodman‟s criterion, is ____
