Page 160 - Cycloid is traced by a point on the circumference of a circle which rolls without slipping along a straight line.

Page 332 - In this regard, the acceleration is directly proportional to the square of the velocity and inversely proportional to the radius of the turn. By common usage, where the axis of rotation is external to the body, as in an aircraft turn or a centrifuge, the acceleration is frequently termed "radial" acceleration, while the term "angular" is better retained for situations where the axis of rotation passes through the body.
