Question

Where does involute gear is used?

(a) For crude purposes

(b) General purpose in precision engineering

(c) Where heavy loads comes on machine

(d) Where impact loads comes on machine

The question was posed to me in an interview for job.

My question is taken from Involute Curve in chapter Measurement and Testing of Gears of Engineering Metrology

Answer 1

The correct choice is (b) General purpose in precision engineering

To elaborate: Involute gears are used for general purpose in precision engineering. The cycloidal gears are not used in modern engineering generally, but can be used for some crude purposes where impact and heavy loads come on the machine.
