To determine

Reason for the spiral curve is a useful easement curve

Expert Solution & Answer
Check Mark

Explanation of Solution

The spiral curve makes an exceptional easement curve because the radius is reduced to infinity of the curve where the tangent of the curve meets.

The easement of the curve is achieved by the spiral curve when the curvature at the junction of the tangent of a circular curve reduces to the sudden changes.

Conclusion:

The easement of the curve is best provided by the spiral curve due to its decrease in radius.
