Explanation:

Given A road curve is banked so that there is no side thrust on the passengers in a car which negotiate the curve at 72 km/h speed. Find the angle of banking for a circular curve making a 90 ° turn in a distance of 157 m along the road.

  • Given v = 72 km / h = 72 x 5/18  
  •                                   = 20 m/s
  • In a distance the circular curve makes a 90 degree turn at a distance of 157 m along the road.
  • Area of sphere is equal to radius of sphere x π times square of diameter.
  •                       So 2 πr / 4 = 157 (length of arc)
  •                      So 2πr = 628
  •                      Or r = 100 m
  • Now tan theta = v^2 / rg
  •                        = 400 / 100 x 9.8
  •                        = 0.408
  •        Or theta = tan^-1 (0.408)
  •                         = 22.19 degree
