Question

The ratio of the pitch circle diameter in millimeters to the number of teeth, is called circular pitch.

(a) True

(b) False

I had been asked this question in quiz.

I'm obligated to ask this question of Systems of Gear Teeth topic in section Toothed Gearing & Gear Trains of Machine Kinematics

Answer 1

The correct option is (b) False

For explanation I would say: Diametral pitch is the ratio of number of teeth to the pitch circle diameter in millimetres.

Circular pitch is the distance measured on the circumference of the pitch circle from a point of one tooth to the corresponding point on the next tooth.
