A pair of helical gears is used with the following properties: 14.5 degree normal pressure angle, 45 degree helix angle, diametral pitch of 8 teeth/in, 1.5-in face width, and normal diametral pitch of 11.31 teeth/in. The pinion has 12 teeth and a 1.5in pitch diameter, and the gear has 32 teeth and a 4.0 in pitch diameter. Both gears have full-depth teeth. If a right-hand pinion and a left hand gear are placed in mesh, find the transverse contact ratio, the normal contact ratio, the axial contact ratio, and the total contact ratio.
