Virtual Procedure

1. Adjust the values of the applied stress components using the corresponding sliders.
2. Change the orientation angle ($\theta$) of the stress element using the angle slider.
3. Observe the calculated principal stresses ($\sigma_1$ and $\sigma_2$) displayed in the results table.
4. Compare the principal stresses for different combinations of applied stresses and orientations.
5. Repeat the procedure with different input values to study the effect of stress transformation.
