Challenge Problems
Push your limits with challenges.
Question 1
Given the initial stress matrix [[4, 2, 0],[2, 3, 1],[0, 1, 5]] and a rotation of 30 degrees, calculate the new stress matrix.
💡 Hint: Remember to use matrix multiplication and the trigonometric values for rotation.
Question 2
After finding the new stress matrix, verify traction on a plane defined by the normal vector [0, 1, 0]. What does this tell you about the stress distribution?
💡 Hint: Use the dot product and stress matrix interactions.
