Question

a) What is banking of roads?
b) With neat diagram, derive equation for the maximum velocity of a car on a banked road.
c) What is optimum speed of the car along the banked road?​

Answer 1

Answer:

a) Banking of the road is raising the outer end of the road higher than the inner end.

b) refer to the attachment

c) Optimum speed is the speed with which one can take turns on banked roads without wear and tear. Note: When a vehicle is moving along a curved path it requires centripetal forces along the curve so that it does not tend to skid over the road. ... We see the angle of banking is independent of the mass of the vehicles

Answer 2

Explanation:

Banking of the road is raising the outer end of the road higher than the inner end. In simple words, banking on the road is making its surface slant. When a vehicle takes a turn on a flat curved road, it must undergo a circular motion. Therefore, the vehicle must have a centripetal acceleration

Centripetal force (mv2r) - acting towards the center of the circular path followed by the car. ... This is an expression for maximum speed of a car on a banked road in circular motion.

Optimum speed is the speed with which one can take turns on banked roads without wear and tear. Note: When a vehicle is moving along a curved path it requires centripetal forces along the curve so that it does not tend to skid over the road.
