Two straight metallic strips each of thickness t and length l are rivetted together. Their coefficients of linear expansions are` alpha_(1) "and" alpha_(2) `. If they are heated through temperature `DeltaT`, the bimetallic strip will bend to form an arc of radius

A bimetallic strip is formed out of two identical strips, one of copper and the other of brass. The coefficients of linear expansion of the two metals are alpha_(c) and alpha_(B) . On heating, the temperature of strip increases by DeltaT and the strip bends to form an arc of radius R. Then R is proportional to

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 temperature of the strip goes up by △T the strip bends to form an are of radius of curvature R . Then R is

A bimetallic is made of two strips A and B having coefficients of linear expansion alpha_(4) and alpha_(B) . If alpha_(A) lt alpha_(B) , then on heating, the strip will

Two rods of lengths L_(1) and L_(2) are made of materials whose coefficient of linear expansion are alpha_1 and alpha_2 . If the difference between the two lengths is independent of temperature.
