Question

Which of the following is not a method of shear test?

(a) Double sheer system for round bar

(b) Double knife shear system for rectangular section

(c) Double shear system for conical surfaces

(d) Shearing of disc using punch and die

I have been asked this question in an online interview.

My question is from Mechanical Tests on Metals, Protection Against Wear in division Wear of Metals, Mechanical Properties and Testing of Engineering Material & Metallurgy

Answer 1

The correct answer is (c) Double shear system for conical surfaces

Explanation: There are basically three main systems for shear tests. First is a double shear system for round bar test-pieces using a fork and eye device. Second is a double knife shear system for a specimen of rectangular section. Lastly, the shearing of a disc from sheet materials using a punch and die.
