WebGears are used for transmitting power from one part of a machine to another. On a bike you push the pedal which in turn will spin the wheels How do gears work? As the first gear turns, it forces the second gear to turn in the opposite direction. By Newtons Third Law, the forces on the teeth of the gears are equal and opposite. Web1 In cars as well as bicycles, when we are on a lower gear, the driving wheel (the one on the wheels) has a bigger radius compared to when on a higher gear. So on a lower gear the bike/car would move lesser compared to the …

WebNov 3, 2024 · Thinking of gears as levers shows exactly how they work. Suppose you turn the axle at point (1). The bar connecting points (1) and (2) moves faster and with less force at point (2) because it's working as a lever. If you can't see this, suppose the red bar were a spanner and you pushed at point (2) to undo a nut at point (1) in the center. in addition to let you know
