![(1) The rated speed of a highway curve of 100m radius is 65kph. If the coefficient of friction
between the tires and the road is 0.60, what is the maximum speed at which a car can maneuver
the curve without skidding? (10 points)
(2) At station 3 + 020 the side slope of a road fill is 2:1. The width of the roadbed (including shoulder
ditches) is 7m and the height of fill at the road center is 3m. The ground slope 8% upward to the
right. At station 3+ 120 the cross section for the road is presented with a road width of 6m.
