8 The square ABCD made of 4 metal rods AB BC CD and DA with point A and C remain fixed AB and AD have coefficient of linear expansion a and are heated by temperature t C BC and CD have coefficient of linear expansion a2 and are heated by t C tz t so that B and D move on perpendicular bisector of AC The temperature difference is proportional to SO
