• Differential GearsWhen a car turns, the outside driven wheel travels a longer arc than the inside wheel, so it must rotate faster. A differential lets the two axle shafts turn at different speeds while both are driven by one input.
• Four-Stroke Engine CycleA fourstroke piston engine completes one thermodynamic/mechanical cycle in four piston strokes and two crankshaft revolutions:
