1.	Two similar iron and copper strips are riveted together at 20^(@)C. What will be the nature of curvature of this bimetallic strip at 0^(@)C and 100^(@)C? (coefficient of linear expansion of copper is more than that iron)
Answer» at both the temperatures the COPPER plate will be on the convex side at both the temperatures the iron plate will be on the convex side at `0^(@)C` the copper plate will be on the convex side but at `100^(@)C`, it will be on the CONCAVE side at `0^(@)C` the iron plate will be on the convex side but at `100^(@)C`, it will be on the concave side.
