Challenge Problems
Push your limits with challenges.
Question 1
Given a skew-symmetric tensor: W = [ 0 -1 2; 1 0 -0; -2 0 0], derive the axial vector and the angle of rotation.
💡 Hint: Start by identifying non-zero elements in W.
Question 2
In a material experiencing shear and local rigid rotation simultaneously, calculate the isolated effect of rotation on the angle given an axial vector representation.
💡 Hint: Visualize how rotation happens even while shear is present.
