The principle is that different materials expand by different amounts when a given amount of heat is applied.
If two strips of metal are bonded together and heated then one will expand more than the other. Because they are bonded the only way this can happen is if the bonded pair curl and curve. So the metal on the outside of the curve covers more distance and is longer than the metal on the inside of the curve.
By arranging things correctly this property can be used to turn on and off an electrical circuit among other things.

What is the Operating principle of a bimetallic strip?
A bimetallic strip is used to convert a temperature change into mechanical displacement.
What is bimetallic strip made of?
A bimetallic strip is made out of steel and iron
What is a bimetallic strip and where can it be used?
A bimetallic strip is a strip with two metals bonded together. It can be found in thermostats
Which two metals are used in bimetallic strip?
A bimetallic strip is made out of copper and steel.
Is bimetallic strip used in clocks?
YES!

What happens when bimetallic strip is heated?
The bimetallic strip bends.
What is bimetallic strip made of?
A bimetallic strip is made out of steel and iron

Which two metals are used in bimetallic strip?
A bimetallic strip is made out of copper and steel.
Many thermostats use m strip?
Bimetallic strip
Can anyone explain the use of a bimetallic strip in heat regulation in an electric iron?
When the temperature of the iron increases, the bimetallic strip bends upwards. This breaks the contact between the strip and the heating coil. When the temperature falls, the bimetallic strip bends down and the contact is restored.
Does the bimetallic strip bend when heated?
yes
Is bimetallic strip used in clocks?
YES!
Does a barometer use a bimetallic strip?
yes
Which two metals are used in a bimetallic strip?
A bimetallic strip usually consists of steel and copper. In some cases brass is used instead of copper.
Why are bimetallic strips used in thermostats?
The two metals chosen for the bimetallic strip have different modulii of thermal expansion, The bimetallic strip bends as the temperature changes and so the strip can be used to activate relays or other electronic switches and so work as a thermostat.
