A plane-strain compression (forging) of a block is shown in the figure. The strain in the z-direction is zero. The yield strength (
) in uniaxial tension/compression of the material of the block is 300 MPa and it follows the Tresca (maximum shear stress) criterion. Assume that the entire block has started yielding. At a point where
