Even riderless bicycles are stable if given enough forward velocity. Much effort has gone into analyzing … WebbGears. Gears, similar to levers, multiply the effect of a turning force using moments. They consist of wheels with toothed edges that rotate on an axle or shaft, which acts as the pivot. The teeth of one gear fit into the teeth of another gear. This lets one gear turn the other, meaning one axle or shaft can be used to turn another shaft. flag go chemo

"WebbGears. Chain transmission. Gears are a mechanical system made of two discs with teeth that mesh smoothly into one another. The two gears are in contact at all times as a tooth of the driver gear pushes a tooth of the driven gear. The driver gear transfers its rotational movements to the driven gear, but the gears turn in opposite directions. " - Physics of bike gears
