- **Principal Stresses**:
The given principal stresses are 80 MPa, 30 MPa, and -40 MPa.
- **Maximum Shear Stress**:
To calculate the maximum shear stress, we use the formula:
\[ \text{Maximum Shear Stress} = \frac{1}{2} \times (\text{Maximum Principal Stress} - \text{Minimum Principal Stress}) \]
Substitute the given principal stresses into the formula:
\[ \text{Maximum Shear Stress} = \frac{1}{2} \times (80 - (-40)) = \frac{1}{2} \times 120 = 60 \text{ MPa} \]
Therefore, the maximum shear stress in this case is 60 MPa.
