Question

In testing of mechanical properties of material, torsion test is more preferred than the tension test.

(a) True

(b) False

I had been asked this question in examination.

I want to ask this question from Testing of Mechanical Properties in section Inspection Testing in Foundries of Casting-Forming-Welding I

Answer 1

Right answer is (a) True

The best I can explain: The torsion test is more preferred than the tension test because shear stress and shear strain are found directly in the torsion test, rather than tensile stress and tensile strain as in the tension test. And all the deformations of ductile materials are by shear, so the torsion test is more fundamental.
