A railroad curve is to be laid out on a circle. What radius should be used if the track is to change direction by 25 0 at a distance of 40 meters?

Question

Philoid · Accepted Answer

Given length of arc = 40 m

And θ = 25°

We know that 180° = π rad ⇒ 1° = π/ 180 rad

We know that

= 91.64 m

So, the radius of the track should be 91.64 m.
