All calculated diameters d are full shafts, for conversion to hollow shafts see "Properties of sections part 2".

Standard shaft diameters are: 25, 30, 35, 40, 45, 50, 55, 60, 70, 80, 90, 100, 110, 125, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500 mm
