Question & Answer
Q:

The angle turned by the gear from the beginning to the end of engagement of a pair of teeth is called ______________

A) angle of approach B) angle of recess
C) angle of action D) angle of contact
 
Answer & Explanation Answer: D) angle of contact

Explanation: Angle of action is the angle turned by the gear from the beginning to the end of engagement of a pair of teeth. Angle of action = Arc of contact / r; where r is the radius of the pinion.
