A vehicle weighing a 50 kN is moving at a constant speed around a circular curve. Neglecting the friction between the tires and the pavement and the centrifugal ratio (the ratio of the centrifugal force experience by the vehicle on the curve to its own weight) is 0.30. The degree of the curve is 5 degrees. a. Calculate the centrifugal force. b. Calculate the maximum speed the vehicle could move around the curve (in kph) c. If the skid resistance is 0.15, calculate the maximum super elevation that can be provided for the speed calculated from b.
