Consider the vertical rear window of an automobile that has a thickness L= 9 mm and height H=0.5 m with heating wires that create uniform volumetric heating. The window interior is exposed to ambient air at 10°C and the window exterior to air at -10°C which moves in parallel flow over the surface with a velocity of 20 m/s. The surface temperature of the window exterior is 12°C. Find the volumetric heating rate necessary to keep the window interior at 16°C. What is the convective heat flux for the interior and exterior of the window?

Consider a Bevel Gear Differential used to drive the rear wheels in an automobile. Assume the input angular velocity is to the carrier and the output angular velocities drive the left and right wheels. If both wheels rotate at the same speed, what is the angular velocity of the planet gear? None of these. The same angular velocity as the carrier The same angular velocity as the wheels. The planet gears have zero angular velocity relative to the carrier.
