1.Consider the flow of a gas between two parallel plates. If there were an increase in temperature due to heat transfer along the flow direction, the gas density would decrease. Assume the viscosity is unaffected. How will the velocity and pressure distribution change from the case with constant density. Sketch the pressure distribution and give the rationale for your result.
2.Pinion gear A rolls on the fixed gear rack B with an angular velocity = 8 rad/s. Determine the velocity of the gear rack c . Assume the direction to the right as positive.
Radius = .3 ft
3.A bowling ball is cast on the "alley" with a backspin of = 12 while its center has a forward velocity of = 7
Radius= 120 mm
Determine the velocity of the contact point in contact with the alley. Assume the direction to the right as positive.
