1.	By an equation how can you define a cycloid?(a) y = a(1-sin α)(b) x = a(α – cos α)(c) x = a(α – sin α)(d) x = a(1- sin α)I got this question at a job interview.I'm obligated to ask this question of Curves Used in Engineering Practice topic in section Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» The correct OPTION is (c) X = a(α – sin α) For explanation: CYCLOID is a curve generated by a point on the circumference of a circle which ROLLS along a straight line. It can be described by an EQUATION, y = a(1 – cosα) or x = a(α – sin α).
