SUMMARY
The discussion focuses on calculating normal stress on a cantilever beam using the formula \(\sigma_x = -\frac{M(x)y}{I}\) and the moment of inertia \(I = \frac{bh^3}{3}\). The user calculated the moment of inertia for point A as \(I = \frac{8th^3}{3}\) and derived the normal stress as \(\sigma_x = -\frac{3\tau_0}{4th}\). The user questions the equivalence of principal stresses at points A and B, noting the influence of applied traction creating a moment around the beam's fixed end.
