What is road banking?

Answer 1

* It provides necessary centrpetal force to avoid skidding while moving on curved path/road. * The outer edge of road of width d at curved path is above at a height h with respect to inner edge, then tan a=h/d= v2/rg where a is angle of banking

Answer 2

The normal reaction, R, now has a component acting towards the centre of the circular path.

If the angle, q, is just right, the correct centripetal acceleration can be provided by the horizontal component of the normal reaction.

This means that, even if there is very little force of friction the vehicle can still go round the curve with no tendency to skid.
to avoid falling in or out of road with inclination or turnings we need banking angle.

Roads are banked because of the inertia of vehicles driving on the road. A car moving at a fast speed has a large inertia, which means that it has the tendency to keep moving in the same direction at the same speed unless a force acts upon it. So when the car hits a curve, it needs a sideways force to push it around the curve, otherwise, it would just keep going straight. The bank in the road tilts the car in the direction of the curve so that its unequally distributed weight will be the force that pulls it around the curve. It is literally falling in the direction of the curve, and gravity is helping it turn. This is the same principle as when you are riding a bicycle. We all know that you do not literally turn a bike so much as lean in the direction you want to go, and the bike will change its course.

Answer 3

Road banking, also known as camber, refers to the slope provided to roads to help vehicles negotiate curves more safely and effectively. The slope is designed to counteract centrifugal forces and keep vehicles from skidding off the road. Proper road banking is essential for maintaining safety and stability during turns.
