Question 1
For each of the four vertical curves show in the attachment (click here for attachment) calculate the following:

K and r

station of BVC and EVC

elevation of point at a distance, L/4, from BVC and EVC

station of turning point

elevation of turning point

elevation of midpoint of each curve
Question 2
Draw a 1/R plot for the following alignment.
The alignment is as follows
Station 0+00 to 12+00 A circular curve to the right (radius = 1000 feet)
Station 12+00 to 14+00 A spiral curve
Station 14+00 to 22+00 A circular curve to the right (radius = 2000 feet)
Station 22+00 to 30+00 A circular curve to the left (radius = 3000 feet)
Station 30+00 to 35+00 A spiral curve
Station 35+00 to 40+00 A tangent segment
Calculate the k value for the second spiral curve.
