Four rods \( A, B, C, D \) of same length and material but of different radii \( r, r \sqrt{2}, r \sqrt{3} \) and \( 2 r \) respectively are held between two rigid walls. The temperature of all rods is increased by same amount. If the rods do not bend, thenhttps://bit.ly/YTAI_PWAP https://www.pw.live
