## Question 68

Applied Mechanics and Design
Stress and Strain

Appeared in Year: 2019

### Question

MCQ▾

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 MPa (compressive) and , the stress component is
