Question

What type of material is used for Gudgeon pin?

(a) Cast iron

(b) Aluminium

(c) Steel alloy of high strength

(d) Hardened and ground steel

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

I'd like to ask this question from Automobile Engineering in section Internal Combustion Engines of Automobile Engineering

Answer 1

Right choice is (c) Steel alloy of high strength

For explanation I would say: Gudgeon pins are made of steel alloy of high strength. Gudgeon pins are short hollow pipes. Steel alloy of high strength are used for this pin because it should be very light and also have very high strength and temperature resistance.
