Question

Why outer edge of the road is kept higher than inn
er edge (banking of road)? Explain.​

Answer 1

Explanation:

HEYYY............

ANSWER____

When a car takes a turn, centripetal force is needed to keep it in its curved track.

The friction between the tyres and road provides the necessary centripetal force.

The car would skid away if the force of friction between the tyres and the road is not sufficient enough particularly when the roads are wet.

Banking of a road means that the outer edge

Banking of a road means that the outer edge of a road is raised. Banking causes an component of vehicle’s weight to provide the necessary force while taking a turn.

Thus banking of road prevents skidding of vehicle

Thus banking of road prevents skidding of vehicle and thus makes the driving safe.

Answer 2

$\mathfrak{\huge{\green{\underline{\underline{AnswEr :}}}}}$

The circumstances of raising outer edge of the curved road above the inner edge is to provide necessary centripetal force to the vehicles to take a safer turn and the curved road is called $\mathtt\red{Banking \: of \:Roads.}</p><p>$

Φ $\large{\boxed{\blue{Forces\:\:involved\:\:in\:\:this}}}$

1. The weight ‘Mg’ acting vertically downwards.
2. The reaction ‘R’ of the ground to the vehicle acting along normal to the banked road OA in upward direction.
3. The vertical component R.Cos θ of R will balance the weight of the vehicle.
4. The horizontal component R.Sin θ of R will provide necessary centripetal force to the vehicle.
