Problem 1: A small truck with a center of gravity at X=2.5ft and Y=6ft is traveling on a circular path of radius R=400ft and e=4% where e=rate of superelevation. Determine the maximum safe speed to avoid both slipping and overturning.
Problem 2: School buses are claimed to be a traffic blessing, especially during the morning peak hours. Assuming that the morning trip is composed of: 70% work trips and others 20% educational trips using school buses carrying 60 students each (1 bus=2.5 EPC) 10% other purposes Also assuming that the replacement for school bus is a " ride sharing minibus".
