Mid Ordinate when Offsets from Long Chord is Used for Setting Out Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mid Ordinate = Radius of Curve for Mid Ordinate-sqrt(Radius of Curve for Mid Ordinate^2-(Length of Long Chord/2)^2)
L_mo = R_{Mid Ordinate}-sqrt(R_{Mid Ordinate}^2-(C/2)^2)
This formula uses 1 Functions, 3 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

Mid Ordinate - (Measured in Meter) - Mid Ordinate is the distance from midpoint of curve to midpoint of chord.
Radius of Curve for Mid Ordinate - (Measured in Meter) - Radius of Curve for Mid Ordinate is the radius of a circle whose part, say, arc is taken for consideration.
Length of Long Chord - (Measured in Meter) - Length of Long Chord can be described as the distance from point of curvature to point of tangency.

STEP 1: Convert Input(s) to Base Unit

Radius of Curve for Mid Ordinate: 40 Meter --> 40 Meter No Conversion Required
Length of Long Chord: 65.5 Meter --> 65.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_mo = R_{Mid Ordinate}-sqrt(R_{Mid Ordinate}^2-(C/2)^2) --> 40-sqrt(40^2-(65.5/2)^2)

Evaluating ... ...

L_mo = 17.0339925106692

STEP 3: Convert Result to Output's Unit

17.0339925106692 Meter --> No Conversion Required

FINAL ANSWER

17.0339925106692 ≈ 17.03399 Meter <-- Mid Ordinate

What is Setting Out using Offsets from Long Chord?

Setting out a curve means locating various points at equal and convenient distances along the length of a curve. The methods of setting out a simple circular curve are broadly classified as linear and angular methods. In the former method, only a chain or a tape is used and no angle measuring instrument is used. In the latter method, an angle-measuring instrument, such as a theodolite is used. The offset from a long chord is one of the linear techniques used. Once the mid ordinate is known, the offset at any distance x from the midpoint can be calculated and thus a curve can be set out.
