CM 3 CESURV30: Corrections Due to Slope, Alignment, Tension, & Sag Flashcards
1
Q
Correction due to slope: formula for gentle slope
A
d = s - Ch; Ch = h^2/2s
2
Q
Correction due to slope: formula for steep slope
A
d = s - Ch; Ch = h^2/2s + h^4/8s^3
3
Q
Correction due to slope: formula for very steep slope
A
to get Theta:
sinTheta = h/s
d = scosTheta;
Ch = s(1-cosTheta)
4
Q
How to check for percent of slope?
A
h/s * 100
