List of top Geology and Geophysics Questions on Stress, Strain, and Material Response asked in GATE GG

A stress tensor $\sigma$, with elements in MPa, is as given. The maximum value of the principal stress in MPa is \[ \sigma = \begin{bmatrix} 1 & 0 & \sqrt{2}
0 & 1 & 0
\sqrt{2} & 0 & 0 \end{bmatrix} \]

A cylindrical sample of granite (diameter = 54.7 mm; length = 137 mm) shows a linear relationship between axial stress and axial strain under uniaxial compression up to the peak stress level at which the specimen fails. If the uniaxial compressive strength of this sample is 200 MPa and the axial strain corresponding to this peak stress is 0.005, the Young's modulus of the sample in GPa is _______ (in integer).

The dimension of dynamic viscosity is:
