按照我国交通规则,汽车、行人要靠右走。但是人们发现,双轨火车是靠左行的,这是为什么呢?人们知道,地球近似球体,自西向东转,赤道附近的线速度约460m/s,南北两极轴心的速度几乎为零。我国地处北半球,当两列火车相遇时,火车靠左行,西边轨道上的火车受的力向西,东边轨道上的火车受的力向东,由于它们受的力都向外侧,火车才不会相撞。反之,如果火车靠右行,火车受的力都向内 In accordance with our traffic rules, cars, pedestrians should go right. However, people found that the double-decker trains are on the left. Why? People know that the approximate sphere of the Earth, turning from west to east, has a linear velocity of about 460 m / s near the equator, and the speeds of the north and south poles are almost zero. Our country is located in the northern hemisphere. When two trains meet, the train is on the left and the train on the west is subjected to westward force. The train on the east orbit is forced to the east. Because of the force they are facing to the outside, Will not collide. On the contrary, if the train is on the right, the force of the train is inward
