Scientific Temperament: Cycle Rickshaw Rear Wheels
Просмотров 8863 года назад
This explains why driving a cycle rickshaw (Tricycle) becomes difficult compared to a bicycle. The rear wheels of a tricycle are arranged such that the one of them is fixed on the axle and the other is kept free. This is done so that the two wheel can traverse different distance on a turning. The difficulty for the driver is derived from the moment generated due to the force on the fixed wheel.
