Question

The compressive test is done on which of the following materials?

(a) Cast iron

(b) Aluminum

(c) Gold

(d) Thermocole

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

This interesting question is from Mechanical Tests on Metals, Protection Against Wear topic in section Wear of Metals, Mechanical Properties and Testing of Engineering Material & Metallurgy

Answer 1

Right answer is (a) Cast iron

Best explanation: Since brittle materials are unsuitable for tension test, they are checked using a compressive test. Brittle materials such as cast iron, concrete, mortar, brick, and ceramics are commonly tested in compression.
