Two spur gears in mesh have a module of 2.5 mm, a magnitude of speed ratio of 0.6, and a centre distance of 50 mm. how many teeth do the gears have? if the pinion is rotating at 1200 rpm, what is the magnitude of the pitch line velocity

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
