In a tensile test, a test piece of 25 mm diameter is tested over a gauge length of 125 mm. The elongation over this length is 0.0875 mm under a pull of 68,725 N. In a torsion test, a test piece was made of the same material and of same diameter and it twisted 0.025 rad. Over a length of 250 mm at a torque of 0.3068 kNm. Find Poisson's ratio and three elastic modulii of the test piece material.

In a tensile test, a test piece of 25 mm diameter is tested over a gauge length of 125 mm. The
elongation over this length is 0.0875 mm under a pull of 68,725 N. In a torsion test, a test piece was
made of the same material and of same diameter and it twisted 0.025 rad. Over a length of 250 mm
at a torque of 0.3068 kNm. Find Poisson's ratio and three elastic modulii of the test piece material.
