Figures below shows different views of a double-reduction gear train with an idler. In this set Gear Dis an idler. Tooth numbers are as given in figure (left) below. All gears are full depth with a pressure angle ϕ = 20^o, and have the same module, m = 5 mm.If the shaft carrying gear Arotates at 1750 rpm clockwise, 

1.  

2. Determine the speed and the direction of rotation of the shafts carrying gears C; D, and E

    

3. If the input power, H_in = 15 kW, estimate the magnitude and direction of the torque transmitted by each shaft (i.e., T_aA, T_bB, T_bC, T_cD, and T_dE in [N-m]). You may neglect friction losses from one gear to the other.
