Stress, Strain and Hooke's Law - Lesson - TeachEngineering
Replacing force with a measure of stress and displacement with a measure of strain, the following expression may be obtained, σ = E* ε. We will now explore the measures of stress and strain. Stress is a measure of average force per unit area, given by σ = F/A where average stress, σ, equals force, F, acting over area, A.
