Cycloidal Curves

Listed for Class 11 Accountancy under the parent chapter “Engineering Curves,” this topic introduces the cycloidal curve formed by a fixed point on a circle as the circle rolls along a straight line without slipping. Students learn its defining features, understand the rolling-motion concept, and study how to construct or represent the curve accurately. The topic also builds visual and geometric reasoning useful for interpreting technical diagrams, while the subject classification should be checked against the intended curriculum.
