SUMMARY
The discussion focuses on the sign convention used in Mohr's Circle for stress analysis. Participants confirm that in Mohr's Circle, normal stress (σ) is considered positive when acting to the right, while shear stress (τ) is positive when acting downward. Additionally, the clockwise orientation for angles (θ) is accepted as positive, contrasting with the traditional counterclockwise convention. This clarification is essential for accurately interpreting stress states in engineering applications.
