Question
Determine principle stresses and the maximum shear stress based assuming normal and shear stress a At in the picture. Draw mohrs circle with max shear and principle stresses and average normal stress.
### Stress and Shear Stress in Materials

**Normal Stress (\(\sigma_A\))**

- \(\sigma_A = -20 \text{ ksi}\)

This value indicates a compressive stress of 20 ksi. In engineering, negative values typically represent compressive stress, meaning the material is being compressed.

**Shear Stress (\(\tau_A\))**

- \(\tau_A = +10 \text{ ksi}\)

This value indicates a shear stress of 10 ksi. Positive values usually signify that the material experiences shear in a specific direction.

These values are critical in evaluating the structural integrity and failure conditions of materials under different kinds of loadings. Understanding the behavior of materials under such stresses aids in the design and analysis of various engineering structures.
