Calculate minimum diameter of shaft subject to bending by point load using AS1403 formula 1 (no tension & no torsion).
Safety factor
$$ F_S = 2 \:
$$
Yield stress
$$ F_Y = 300 \:
MPa $$
$$ D_{shaft_{min_p}} = {\left({ {F_S \over F_Y} \cdot M_{B_p} \cdot 10 ^ 4 }\right) ^ \left({ {1 \over 3} }\right)} \:, mm $$
