5. A car engine powers two front wheels, producing one tire revolution for every four crankshaft revolutions. If the car is moving at 72 mph and has 27 inch diameter tires, what video frame rate would show a mark on one tire as stationary? Would the engine pistons appear stationary if recorded at the same frame rate (assuming the engine block is transparent)? Assume engine drives wheel without any slip.
