7.15 Two left-hand helical gears having the same helix angle are used

7.15 Two left-hand helical gears having the same helix angle are used to connect two shafts 60 apart. The velocity ratio is to be 0.4 and the gears have a normal module of 6 mm. If the center distance is to be about 300 mm, determine the numbers of teeth for each gear.
