(1) The motor delivers a power of 300 W through the shaft AB while running at 180 rev/min. The resulting torque is transmitted to shaft CD using the gears at E and F. Determine the equilibrium torque T on shaft CD and the minimum diameter of shaft AB. The bearings B, C, and allow free rotation of the shafts. Both shafts are made of an allow having Tallow = 8 MPa and allow = 100 MPa. 40 mm B 40 mm 120 mm
