Question

In a uniaxial tension test, it was found that the gage section of a standard test specimen, fabricated from material A, with an original length of 100 mm and original diameter of 14.33 mm, extended by 0.15 mm when a tensile force of 50 kN was applied to the specimen. In a simple torsion test, it was found that one end of a solid circular rod of material A (diameter = 19 mm and length = 200 mm) twisted by 0.502 degrees with respect to the other end, when a torque of 45 N-m was applied to the rod. The Poisson's ratio of material A is:

A) 0.33
B) 0.37
C) 0.29

Explanation / Answer

C) 0.29
