Wire Elongation Trick: Length vs Diameter in 59 Sec 🔥
❓ Concept 🎬 Mechanical Properties of Solids — Wire Elongation Concept in 59 Sec Same material… same force … phir bhi ek wire zyada stretch karegi! 👉 Reason length mein hai ya thickness mein? 🤯 Is concept ko pakad liya, toh ratio-based elasticity questions turant ho jaate hain 🔥 🖼️ Concept Image ✍️ Short Explanation Elasticity ke questions mein formula se zyada dependence matter karta hai. Yahan ek hi idea kaam karta hai: 👉 Elongation kis cheez par depend karti hai? 🔹 Step 1 — Elongation Formula (FOUNDATION 💯)** For a stretched wire: Δ L = F L A Y \Delta L=\frac{F\,L}{A\,Y} Where: F F = applied force L L = length A A = cross-sectional area Y Y = Young’s modulus 📌 Core idea: elongation depends on L and A . 🔹 Step 2 — Same Material ⇒ Same Y Y ** Given: both wires are of the same material . So: Y A = Y B ⇒ Y cancels in ratio Y_A = Y_B \quad \Rightarrow \quad Y \text{ cancels in ratio} ...
