When a bimetallic strip is heated, it

Two metal strips, each of length l and thickness d at temperature T_(0) are riveted together so that their ends coincide. One strip is made of metal A having a linear coefficient alpha_(B) where alpha_(A)gtalpha_(B) . When this bimetallic-strip is heated to a temperature (T_(0)+DeltaT) , one strip becomes longer than the other and the bimetallic strip bends into an arc of a circle. What is the radius of curvature R of the strip ?

A bimetallic strip consists of metals X and Y. It mounted rigidly at the base as shown. The metal X has a higher coefficient of expansion compared to that for metal Y. When the bimetallic strip is placed in a cold bath

What is a bimetallic strip? Where is it used?

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 strip goes up by DeltaT and the strip bends to from an arc of radius of curvature R. Then R is.

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
