The vertical and horizontal two forces are applied as shown to the gears mounted to the solid shaft AB. Knowing that the yield stress of the shaft is 210 MPa and the factor of safety is 2, determine the smallest permissible diameter of the solid shaft AB using maximum distortion energy theory. 150 mm 350 mm F = 5 kN -75 mm 50 mm B F. 75 KN G 250 mm
