A bimetalis strip conists of two metakl strips with diffesrent coefficients of linear expansion `alpha_(1)` and `alpha_(2)` each of small thickness d and length `L_(0)` at `T_(0)`. They are bonded together and, with a change in temperature `DeltAT`, will curve in a circular arc, as shown in figure. Show that the radius of curvature R is given approximately be

`R=d/((alpha_(2)-alpha_(1))DeltaT)`
