When temperature of a rod increases from \(t\) to \(t+\Delta t\) the moment of inertia of the rod about an axis increases from I to I \(+\Delta \mathrm{I}\). If \(\alpha\) be the coefficient of linear expansion of the rod, then the value of \(\frac{\Delta I}{I}\) is 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
