Frequently Asked Questions

Question 1: Explain Hooke's Law.

Answer: Hooke's Law states that stress is directly proportional to strain within the elastic limit of a material. It is expressed as F = kΔL, where F is the force applied, k is the spring constant, and ΔL is the change in length.

Question 2: What is stress and strain?

Answer: Stress is the force applied per unit area, and strain is the relative deformation or change in shape of a material due to stress.
