# Simple Curve Problem

## Simple Curve Problem

(OP)
Hello All,

I have a problem in solve a simple curve problem. Here is the problem..

Two tangents intersect at a chainage of 1000 m, the deflection angle being 36°.The length of the long chord is 133.52 m and the chainage of T2 is 2065.61m. Find the Chainage of T1 and Radius of curve.

Now the point is that when I try to find T1 by this formula:

T1 = Total Chainage - Tangent Length.

Tangent Length found to be 70.2m and Radius = 216.04m , therefore

T1 = 1000 - 70.2 = 929.8m

But But when I try to verify my result using length of curve formula

length of curve = 135.47

So T1 = T2 - length of curve

T1 = 2065.61 - 135.4 = 1929.08

So the difference is about 1000m which is the total chainage. Some one told me that it has to do with dependency. Please anyone help me in solving this problem. May be my Radius is not correct. Some one please help me. Thank you in advance..

### RE: Simple Curve Problem

My advise is to do the problem by either using ACAD or manually with drafting equipment.
