Question

The tangent to both the curves in an ogee curve is perpendicular to each other.

(a) True

(b) False

I have been asked this question in unit test.

My question is taken from Drawing Regular Polygons & Simple Curves topic in section Geometrical Construction of Engineering Drawing

Answer 1

Correct choice is (b) False

To explain: The tangent to both the curves in an ogee curve is parallel and not perpendicular to each other. An ogee curve is a curve with two curves with one of the curve being a reverse curve to the other. Hence it is also called as a reverse curve.
