Question

. What do you mean by banking of roads? What is its need? Make a diagram and derive the

expression of angle of banking when friction is negligible.
​

Answer 1

Answer:  

the phenomenon of raising the outer edge of the curved load above the inner edge is to safer turn is called the banking of road .

Explanation:

fr=nv^2/r= nsin+usNcos..1

fy=

ncos-usNsin-mg...2

vmax=√rg(sin+usNcos)/cos-usSino
