For a pair of gears the allowable contact stress number for the pinion is 72 ksi and the allowable bending stress number for the gear is 50 Ksi Determine
a) The minimum required hardness of the pinion for Grade 2 steel: HB
b) The minimum required hardness of the gear for Grade 2 steel: HB

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.
