What is a bimetallic strip?

Where is bimetallic strip used?

A bimetallic strip of brass and iron is straight at room temperature. When this bimetallic strip is heated it bends, such that:

We would like to perpare a scale whose length does not change with temperature. It is proposed to prepare a unit scale f this type whose length remains, say 10 cm. We can use a bimetallic strip made of brass and iron each of different length (both components) would change in such a way that differnece between theri lenght rermain constant. If alpha_(iron) = 1.2 xx 10^(-5)//K and alpha_(brass) = 1.8 xx 10^(-5)//K, what should we take as lenght of each strip ?

Two identical rectangular strips. One of copper and the other of steel, are riveted together to from a bimetallic strip (alpha_(copper) gtalpha_(steel)) . On heating. This strip will

How is bimetallic strip used in fire alarm?

We use bimetallic strips as thermostat switch.

When a brass-invar bimetallic strip is heated, unequal expansion bends the strip, such that brass takes

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

Statements given below are incorrect. Write the correct statements. A bimetallic strip expands equally on heating and does not bend.
