Two metal strips, one of brass and other of steel are of equal length 1.5 m and equal thickness 0.25 cm. These are put together riveted and clamped at one end at \[0{}^\circ C\]as shown in fig. If the temperature rises to\[50{}^\circ C\], calculate the radius of curvature (in meter) of the combined strip. \[\alpha \] for brass is \[19\times {{10}^{-6}}/{}^\circ C\],\[\alpha \]for steel\[=11\times {{10}^{-6}}/{}^\circ C\].
