Assume that the circular arc of the road can’t be changed.
Suppose the radius of the curve is 50 m. • Speed limit: assume that
the posted speed limit can be changed, to anything between 15 mph
and 70 mph (70 mph is the speed limit on the highway that the
offramp is from) • Friction: the road surface material that is to
be used has a coefficient of friction with tire rubber when dry of
0.75, but only 0.25 when wet, and only 0.05 when icy. • Stability o
even on level road, it’s possible for a vehicle to tip o on a
banked surface, it’s possible for a vehicle to tip out of the turn
and also into the turn
Banked curve, how much degree should the road be banked?
