b) For a particular circular curve of radius 150 m, the road surface has a sideways force coefficient of friction of 0.20. Determine the speed (in km/hr) at which sliding will occur for each of the following three conditions and comment in principle on the possibility of vehicles overturning in these situations. (Assume g = 9.81m/s²). ● The road surface has an adverse crossfall of 2.5% ● The road surface is flat ● The road surface has 6% superelevation (6 marks)
