Tourism is a meaningful activity. On the one hand, it can relieve physical and mental fatigue; on the other hand, it can increase knowledge. Therefore, when we go to holiday, there is always a surge of people in tourist places. Which seat is comfortable on the tour bus? How to choose the safest driver? Xiao Bian brings you to understand.
When we take a tour bus or other large-scale bus, the car turns left and right for a while, and people also shake left and right along the way. After a long time, it makes us dizzy and even carsick. What shall we do?
Some people suggest sitting in the front; others say the middle is better. Which do you think is the most suitable seat?
Now, let's start with the S-shaped curve. The path of the front wheel is different from that of the rear wheel. The rear wheel is closer to the inside, and the turning distance is shorter, so the curvature of the rear wheel is smaller.
From this we can see that the place where the car sways most laterally is in the front. On the contrary, the least lateral sway is in the rear axle. At this time, the rear wheel is the fulcrum of steering, so the farther the rear of the car is from the fulcrum, the greater the degree of shaking.
If the car is walking on the rough road, it will vibrate up and down. The fulcrum of vibration is in the front and rear wheels, so the amplitude between the front and rear wheels is the smallest, that is to say, the up and down vibration is relatively slight.
Therefore, people who don't like left-right shaking can sit near the rear wheel, while people who don't like up and down vibration can sit between the front and rear wheels.
