State Hooke's law and define Young's modulus.
Original Khojo Papers practice question — not from a past board paper.
Answer
Hooke's law states that within the elastic limit the stress in a body is directly proportional to the strain produced. Young's modulus is the ratio of the longitudinal stress to the longitudinal strain of a wire, and its SI unit is the pascal.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Beyond the elastic limit the body does not return to its original shape.
