Challenge Problems
Push your limits with advanced challenges
Given a stress tensor of [[50, 20], [20, 30]], find the principal stresses and explain their significance.
💡 Hint: Use the characteristic equation to solve for eigenvalues.
Analyze a failure scenario where miscalculating principal stresses led to a structural collapse and suggest measures to avoid such failures.
💡 Hint: Consider historical cases where this occurred.
