Deviation Angle given Length of Summit Curve Less than Sight Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Deviation Angle = ((sqrt(2*Driver Sight Height)+sqrt(2*The Height of The Obstruction))^2)/(2*Sight Distance-Length of Curve)
N = ((sqrt(2*h₁)+sqrt(2*h₂))^2)/(2*S-L_s)
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Deviation Angle - (Measured in Radian) - Deviation Angle is the angle between the reference direction and the observed direction.
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.
The Height of The Obstruction - (Measured in Meter) - The Height of The Obstruction refers to its vertical dimension, blocking a line of sight or path, often in transportation, construction or safety.
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.

STEP 1: Convert Input(s) to Base Unit

Driver Sight Height: 32.5 Meter --> 32.5 Meter No Conversion Required
The Height of The Obstruction: 55 Meter --> 55 Meter No Conversion Required
Sight Distance: 186.3277 Meter --> 186.3277 Meter No Conversion Required
Length of Curve: 94.72078 Meter --> 94.72078 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N = ((sqrt(2*h₁)+sqrt(2*h₂))^2)/(2*S-L_s) --> ((sqrt(2*32.5)+sqrt(2*55))^2)/(2*186.3277-94.72078)

Evaluating ... ...

N = 1.23811616290507

STEP 3: Convert Result to Output's Unit

1.23811616290507 Radian -->70.9388306814055 Degree (Check conversion here)

FINAL ANSWER

70.9388306814055 ≈ 70.93883 Degree <-- Deviation Angle
