A right-angle beam undergoes stress. Given its stress matrix in the original system, apply a 45° rotation and derive a new matrix. Verify by calculating the traction on both systems.
💡 Hint: Review your rotation matrix equations.
Using a triangular prism under loading, derive its stress matrix in its local coordinates from global coordinates after a 60° rotation. Verify by calculating the maximum traction on one side.
💡 Hint: Ensure to relate angles correctly for maximum traction verification.
