Inclination Angle given Length of Valley Curve Less than Stopping Sight Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inclination = atan((Deviation Angle*(2*Sight Distance-Length of Curve)-(2*Driver Sight Height))/(2*Sight Distance))
α_angle = atan((N*(2*S-L_s)-(2*h₁))/(2*S))
This formula uses 2 Functions, 5 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)

Variables Used

Inclination - (Measured in Radian) - Inclination refers to the angle or slope of an object or surface concerning the horizontal plane.
Deviation Angle - (Measured in Radian) - Deviation Angle is the angle between the reference direction and the observed direction.
Sight Distance - (Measured in Meter) - Sight Distance is s the minimum distance between two vehicles moving along a curve, when the driver of one vehicle can just see the other vehicle on the road.
Length of Curve - (Measured in Meter) - Length of Curve is the distance along the road where the alignment changes from upward to downward slope, creating a valley-shaped concave.
Driver Sight Height - (Measured in Meter) - Driver Sight Height refers to the vertical distance between the driver's eye level and the road surface while seated in a vehicle.

STEP 1: Convert Input(s) to Base Unit

Deviation Angle: 236.5494 Degree --> 4.1285658736163 Radian (Check conversion here)
Sight Distance: 3.56 Meter --> 3.56 Meter No Conversion Required
Length of Curve: 7 Meter --> 7 Meter No Conversion Required
Driver Sight Height: 0.123396 Meter --> 0.123396 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α_angle = atan((N*(2*S-L_s)-(2*h₁))/(2*S)) --> atan((4.1285658736163*(2*3.56-7)-(2*0.123396))/(2*3.56))

Evaluating ... ...

α_angle = 0.0349065886945188

STEP 3: Convert Result to Output's Unit

0.0349065886945188 Radian -->2.00000020939538 Degree (Check conversion here)

FINAL ANSWER

2.00000020939538 ≈ 2 Degree <-- Inclination
