The helical gear reducer represented in Figure P16.15 is driven at 1000 rpm by a motor developing 15 kW. The teeth have c = 0.50 rad and fn = 0.35 rad. Pitch diameters are 70 mm and 210 mm for pinion and gear. Determine the magnitude and direction of the three components of the gear-tooth force. Make a sketch like the one in the figure except with the shafts separated vertically, and show all tooth force components acting on both gears.
