Question

Which of the following factor is least important for an involute profile?

(a) Number of teeth

(b) Pressure angle

(c) Pitch

(d) Gear it mates with

This question was posed to me at a job interview.

Enquiry is from Involute Curve in section Measurement and Testing of Gears of Engineering Metrology

Answer 1

Right answer is (d) Gear it mates with

To elaborate: The involute gear profile is important in machine design, since unlike with other gear systems, involute gear tooth profile depends on only the number of teeth on the gear, pitch and pressure angle but does not depend on the gear it mates with.
