If the yield point shear stress obtained from the torsion test of a cylindrical specimen is \( \tau_y \), then what is the maximum value of principal strain at yielding? (\( \mu \) is Poisson's ratio and \( E \) is Young's modulus)
If the ratio of Young's modulus to bulk modulus of a material is \( \frac{3}{2} \), then the ratio of shear modulus to the Young's modulus of the material is
