Deflection Angle Method for Circular Curve
The deflection angle method is a commonly used technique in surveying to set up circular curves. It involves calculating the deflection angle at various points along the curve to ensure accurate staking and alignment.
Given Information
- Intersection angle (IA) = 32 degrees
- Length of the curve (LC) = 400 meters
- Distance from the Point of Curvature (PC) to the stake point (SC) = 80 meters
Understanding the Problem
In this problem, we need to determine the subdeflection angle (del A) required to stake a point 80 meters from the Point of Curvature (PC). The subdeflection angle is the angle between the tangent to the curve at the Point of Curvature (PC) and the tangent to the curve at the stake point (SC).
Calculating the Subdeflection Angle (del A)
To calculate the subdeflection angle, we can use the formula:
del A = (IA * SC) / LC
Substituting the given values:
del A = (32 * 80) / 400
del A = 2560 / 400
del A = 6.4 degrees
However, we need to remember that the subdeflection angle is always half of the deflection angle. Therefore, the correct answer would be:
Subdeflection angle (del A) = 6.4 / 2 = 3.2 degrees
Explanation
The subdeflection angle is calculated using the formula (IA * SC) / LC, where IA is the intersection angle, SC is the distance from the Point of Curvature to the stake point, and LC is the length of the curve. In this problem, we substitute the given values and calculate the subdeflection angle as 3.2 degrees.
It is important to accurately calculate the subdeflection angle to ensure proper staking and alignment of the circular curve. The deflection angle method is a reliable technique used in surveying to achieve this.
