2 cards from this section. Quick, good the night before a test.
What is a displacement in mechanics?
Think about how we calculate movement.
Define strain.
Consider the percentage change in dimensions.
What represents a shift in a point in mechanics?
Think about how forces influence object positions.
Total rotation includes contributions from shear strain and rigid rotation. (True/False)
Consider what happens during both shear and structural adjustments.
Given arbitrary displacement functions for a rectangular object, derive a strain matrix and calculate the resulting strains at specific points.
Focus on differentiation for deriving strains from displacement.
A material's displacement yields a regular pattern of strain. Predict how rotations might change as the material deforms based on initial measurements.
Use angle representations to analyze the rotational outcomes.
