Radius = [ answer ] \'
5 points
QUESTION 3
Given a 500’ vertical curve, g1=-1.50%, g2=-0.75%, PVI Station = 6+28.00, PVI elevation of 235.60’. Give station elevations at the PC and PT and every full station. Round to the nearest 0.01\'.
@ Station 3+78.00 = \'
@ Station 4+00.00 = \'
@ Station 5+00.00 = \'
@ Station 6+00.00 = \'
@ Station 7+00.00 = \'
@ Station 8+00.00 = \'
@ Station 8+78.00 = \'

QUESTION 4
Field conditions require a highway curve to pass through a fixed point. Compute an equal tangent vertical curve solving for L (Round to the nearest station).
g1=-3.50%
g2=+1.00%
PVI elevation = 300.00’
PVI station = 40+00.00
Fixed elevation = 303.39’
Fixed station = 43+21.75
L = [ answer ] stations
5 points
QUESTION 5
Given the following conditions, calculate r, station of the PVC, determine if its a high or low point, the high/low station, and the high/low station elevation.
Round r to the nearest 0.1
Round station to the nearest 0.01
Round elevation to the nearest 0.01\'
g1=+3.50%
g2=-1.00%
PVI elevation = 500.00’
PVI station = 20+34.13
L=15 stations
r = %/sta
High or Low?
PVC = +
High/Low Station = +
High/Low Point Elevation = \'
