How does a train stay on the track?
- The pointy part of the wheel is more there as a backup. If it was actually hitting the rail it would make a lot of noise.
- The left and right wheels are connected by a rod, unlike car.
- The wheels are not flat and the rails are also not flat.
- The wheel is larger on the inside than the outside what happens when you meet a curve?
- What happens is the wheel moves to one side and one side the wheel is larger, the other side (since it's connected) gets pushed and shows a smaller wheel.
See this video with Richard Feynman.
