Elastic Deformation, Plastic Deformation and Elastic Limit|| Lecture No 05|| 11th Class physics||

Описание: Welcome to this detailed lecture on Elastic Deformation, Plastic Deformation, and Elastic Limit—crucial topics in Engineering Mechanics and Material Science!

In this video, we cover: ✅ Elastic Deformation — What happens when a material returns to its original shape after stress is removed?
✅ Plastic Deformation — Learn when and why materials undergo permanent change.
✅ Elastic Limit — The boundary between reversible and permanent deformation.

We also explain:
🔹 Proportional Limit — The region where stress and strain follow Hooke's Law perfectly.
🔹 Hooke's Law — "Stress is directly proportional to strain"—understand this fundamental law clearly.
🔹 Ultimate Tensile Strength (UTS) — The maximum stress a material can handle before necking or failure.
🔹 Difference between Ductile Substances (like copper, aluminum) and Brittle Substances (like glass, ceramics).

✨ Whether you're a B.Tech, B.Sc., or competitive exam aspirant, this video gives a complete and simple explanation to strengthen your concepts!
