MATSE 259 Exam 1 PSU Questions and Answers | Latest Version | 2024/2025 | Graded A+ How does strain relate to deformation in materials? Strain is the measure of deformation representing the change in length relative to the original length. What is yield strength? Yield strength is the stress at which a material begins to deform plastically. Why is Young's modulus important in materials science? Young's modulus measures a material’s stiffness, or resistance to elastic d...
