A cylindrical metal component of 10 mm diameter is subjected to uniform uniaxial tension during operation. It was observed that a force of 14 kN produces a uniform reduction of \(3 \times 10^{-3}\) mm in diameter. Assume that material behaviour is homogeneous, isotropic, and linear elastic.
If its Young's modulus is 150 GPa, the Poisson's ratio of the material is ______ (rounded off to two decimal places).
Note: Assume \(\pi = 3.14\).
