What happens to bimetallic strip when it is heated and cooled?
The two metals have different expansion rates when the strip is heated. This means that one of the metals will expand more than the other, causing the strip to bend.
How could a bimetallic strip be used to help in every day life?
A bimetallic strip can be used as a thermometer or thermostat. The two metals expand at different rates which will make it bend. You can use this to find the temperature of an oven. When the temperature of the oven increases, the strip will curve and break the electrical contact which make the oven cool down. When the oven cools the bimetallic strip will become straight again and the electrical contact will be remade and the oven will begin to reheat again.
What is the principel of bimetallic strip?
A bimetallic strip is made from two combined metal strips that have different rates of expansion when heated. This causes the strip to bend and so close or open an electrical contact switch.
Contains a piece of metal that bends when its hot?
A thermostat is the most common item containing a bimetallic strip.
What is the role of the bimetallic strip and how it works in relationship to expansion of metals?
When heat is applied to the end, one of the metals will expand faster than the other and the coil can operate a switch or valve just as the thermocouple does.
What happens when bimetallic strip is heated?
The bimetallic strip bends.
Which direction does a bimetallic strip bend when cooled?
It depends how it has been constructed
What is the Operating principle of a bimetallic strip?
A bimetallic strip is used to convert a temperature change into mechanical displacement.
What happens to bimetallic strip when it is heated and cooled?
The two metals have different expansion rates when the strip is heated. This means that one of the metals will expand more than the other, causing the strip to bend.
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.
How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
What does bimetallic strip mean?
A strip consisting of two metals that bends with a rise in temperature
Why is a bimetallic strip curve when it is heated or cooled?
Because the two metals have different coefficient of linear expansion
Is it possible to use bimetallic strip to find temperature?
because of pressure
What is the element which bends with temperature and is used in thermostatic switches?
Bimetallic strip
What temperature is required for a bimetallic strip to bend?
Any temperature above or below the temperature at which they were glued together.
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.
