A section of a roadway has a horizontal curve with
superelevation of 6% and central angle of 40o. The
design speed of the section is 60 mph. There are two lanes on the
curve, each 12 ft wide. Determine:
(a) The degree of the curve.
(b) The length of the curve.
(c) The minimum distance of an obstruction from the centerline
of the innermost lane.

45-degree angle.
A. Draw an inelastic demand curve and indicate on the graph the
equilibrium price and quantity.
B. Draw a shift in supply(shift out) associated with an increase
in the supply. Indicate on the graph the new equalibrium price and
quantity.

of 5° 18’ 53”. Find the direction and distance from the PC to the
first two station stake on the curve [not counting the PC as one of
the 2].

A horizontal curve on a three-lane highway with 12-ft lanes has
a PC located at station 10+00 and PT at station 13+70. The central
angle is 25 degrees, the superelevation is 4%, and 40 ft of
clearance is available between an obstruction and the centerline.
