4) A sophisticated machinery design has a flat bar fillet component with a thickness of 10mm. For an upgraded version of this machinery,this component is replaced with a flat bar with a hole (without a fillet part). If the thickness of to plate is to be reduced by 20% and allowable stress, largest axial load and stress-concentration factors are to remain same, calculate the values of major width D and hole's radius r for the new component. For the flat bar with fillet: D = 120 mm d = 60 mm r = 8.1 mm Allowable stress = 135 MPa
