Challenge Problems
Push your limits with advanced challenges
A steel beam supports a load causing varying stress distribution. Calculate the principal stresses given the stress matrix:
[(200, 50, 0), (50, 150, 0), (0, 0, 100)] and determine the principal planes.
💡 Hint: Use characteristic polynomial to find the eigenvalues.
A pressure vessel has an internal pressure causing stress; determine the principal stresses if the stress tensor is [300, 120, 0; 120, 220, 0; 0, 0, 90].
💡 Hint: Look into solving determinants for the stress tensor.
