Why does a four wheeler tilts opposit to two wheeler on vertical axis while moving on a curved path?

Question

It is an observation of buses / cars / motor cycles moving on a round about

Answer 1

They all actually would tilt the same way when going around a curve.

On a two wheeler, the driver has the ability to lean into a curve to compensate for the tilt. If they didn't, then they would end up being thrown off or tipping over. Four wheelers cannot tilt into a curve (unless the pavement itself tilts, as at a racetrack). They will tilt to the outside of a curve, and put more weigh on the outside wheels.

If the net force (down and outward) on the center of gravity does not go through the wheel of a two wheeler, it tips over. If that force on a four wheeler goes outsdide the wheel base, it tips over.

Answer 2

It's the sideways force the ground is exerting on the tires that makes you turn instead of going in a straight line. It's the same if you're standing still and someone is pushing your feet to the left. To keep from falling over, you lean to the left. That's the two-wheeler. Or you spread your feet enough so both feet stay on the ground. That's the four-wheeler. But since you can't lean, more 'weight' is on your right foot. For the four-wheeler, more weight is on the springs on the right than on the springs on the left, so they compress more and you lean to the right. It's not actually weight, it's the force of the person pushing you to make you move left. Because that force is applied to your feet instead of your center of mass, the force is tending to rotate you around your center of mass.

Answer 3

Four wheeler is easier, two wheeler is much much safer, on a four wheeler if you roll youre pretty much screwed as you will get crushed. Two wheeler is almost as easy to, if you know how to ride a bike you can ride 2 wheeler.

Answer 4

Because the rider of the two wheeler leans into the curve.

Answer 5

that is bcoz a four-wheeler needs more centripetal force n it takes more time to gain that force.
