366776 A bimetal made of copper and iron strips welded together is straight at room temperature. It is held vertically so that the iron strip is towards the left hand and copper strip is towards right hand. The bimetal strip is then heated. The bimetal strip will \(\left( {{\alpha _{cu}} > {\alpha _{Fe}}} \right)\)

366778 Two metal rods have coefficients of linear expansion \(1.1 \times {10^{ - 5}}/^\circ C\) and \(1.65 \times {10^{ - 5}}/^\circ C\) respectively. The difference in lengths is \(10{\rm{ }}cm\) at all temperatures. Their initial lengths must be respectively .

366779 How much should the temperature of a brass rod be increased so as to increase its length by \(1 \%\) ? (Take, \(\alpha\) for brass is \(0.00002^{\circ} C^{-1}\) )

366780 A wheel is \(80.3\;cm\) in circumference. An iron tyre measures \(80.0\;cm\) around its inner face. If the coefficient of linear expansion for iron is \(1.2 \times {10^{ - 5}}\,^\circ {C^{ - 1}}\), the temperature of the tyre must be raised by
