B) A wind turbine with an electrical generator rated at 200 k W output. The low speed shaft rotates at 40 (r.p.m) and the high speed shaft rotates at 1800 (r.p.m). Solid steel shafts are available with recommended maximum torsional shear stresses of 55 MN/m2. The gearbox efficiency at rated conditions is 0.94 and the generator efficiency is 0.93. Determine the necessary low and high shaft diameters.
