6.5% superelevation will be applied with a transition curve (clothoid) to a horizontal curve which has a point of curvature PC: KM:1+800, elevation:+50.00. Determine the coordinates of middle point of ramp with regards to revolving around inner axis case, and calculate the lateral force effecting a vehicle with 1500 kg weight at the same point.
Hint: Length of clothoid is $L = 60 + ba/2$, carriage way having lateral slopes of $\pm$ 2.5%, includes two-lane-4.0 meter each (2 x 4m), S = 2%
