Two indentical recrangular strips. One of copper and the other of steel, are rivetted together to from o bimetallic strip `(alpha_copper gtalpha_steel)`. On hearing. This strip will

Two identical thin metal strips one of aluminium and the other of iron are riveted together to form a bimetallic strip. The temperature is raised by 50^(@)C . If the central planes of the two strips are separated by 2nm and the coefficients of thermal expansion of aluminium and iron are respectively 30 xx 10^(-6)//^(@)C and 10 xx 10^(-6)//^(@)C the average radius of curvature of the bimetallic strip is about

A bimetallic strip is made of aluminium and steel (alpha_(Al)gtalpha_(steel) . On heating, the strip will

A bimetallic strip is formed out of two identical strips one of copper and the other of brass. The co-efficients of linear expansion of the two metals are alpha_(C) and alpha_(B) . On heating, the the strip bends to form an are of radius of curvature R . Then R is
