Example:
G1 = 2.5%
G2 = 1.5%
Length (L) = 100 Ft. or whatever.
So it will be a CREST Vertical Curve.
1. How do we calculate the Algabraic(A)Difference in grades? Is it just 1.0%? And what is a algabraic difference? Can there be a negative Algabraic Difference.
2. K = L/A Is this the Correct Formula?
Thanks.
