Challenge Problems
Push your limits with challenges.
Question 1
Given arbitrary displacement functions for a rectangular object, derive a strain matrix and calculate the resulting strains at specific points.
💡 Hint: Focus on differentiation for deriving strains from displacement.
Question 2
A material's displacement yields a regular pattern of strain. Predict how rotations might change as the material deforms based on initial measurements.
💡 Hint: Use angle representations to analyze the rotational outcomes.
