In a bimetallic strip, two metals are bonded together, and when the strip is heated, one metal expands more than the other, causing the strip to bend.
The metal that expands more in a bimetallic strip is typically the one with a higher coefficient of thermal expansion. This means that it will expand more for a given temperature increase.
For example:
In general, metals like aluminum and brass tend to have higher thermal expansion than metals like steel or iron.
The metal that expands more in a bimetallic strip is typically the one with a higher coefficient of thermal expansion. This means that it will expand more for a given temperature increase.
For example:
- Aluminum expands more than steel when heated, so in a bimetallic strip with aluminum and steel, the strip will bend with the aluminum side on the outside because aluminum expands more.
In general, metals like aluminum and brass tend to have higher thermal expansion than metals like steel or iron.
