A rail road curve is to be laid out on a circle
what radius should be used if the track is to change direction by 25 degrees in a distance of 120 m?
:
25 degrees represent 120 m part of circumference
25%2F360C = 120
25C = 360*120
C = 43200%2F25
C = 1728 meters
Find the radius of circle with this circumference
2%2Api%2Ar = 1728
r = 1728%2F%282%2Api%29
r = 275 meters is the radius for a 25 degree arc of 120 meters
