Bimetallic strips are commonly used as temperature-sensitive sensors in devices that require automatic temperature regulation, such as thermostats. The bimetallic strip bends in response to temperature changes, making it a useful component for on/off control systems where temperature is a key factor.

How does the concept of linear expansion help the fabrication of bimetallic strips Explain the working g of bimetallic strips in a thermostats?
The concept of linear expansion is used in bimetallic strips to create a temperature-sensitive component. Bimetallic strips are made by bonding two different metals with different coefficients of thermal expansion. When exposed to temperature changes, the metals expand or contract at different rates, causing the strip to bend. In a thermostat, this bending action controls an electrical switch, regulating the temperature by turning a heating or cooling system on and off.
Why are bimetallic strips used in thermostats?
Bimetallic strips are used in thermostats because they have the property of bending or curving when heated or cooled. This bending action is utilized to open or close electrical contacts in the thermostat, triggering the heating or cooling system to turn on or off based on the temperature changes.
What is the two metal pieces in a thermostat?
The two metal pieces in a thermostat are typically made of bimetallic strips. These strips have different coefficients of thermal expansion, causing them to bend in response to temperature changes. When the temperature reaches a certain point, the bimetallic strips cause the thermostat to switch on or off.
Appliances bimetallic strips are used in?
Bimetallic strips in appliances are commonly used in thermostats to regulate temperature. As the temperature changes, the bimetallic strip bends, causing it to open or close an electrical circuit to control the appliance's heating or cooling functions. This mechanism helps maintain a consistent temperature within the appliance.
What is bimetallic strips used for?
Bimetallic strips were commonly used in thermostats. The two metals would expand at different rates and therefore bend. When a bimetallic strip, made of iron and brass [or any other metals] is heated, both metals expand differently, causing the bimetallic strip to bend. These bimetallic strips are used in fire alarms. The heat of the fire, causes the brass and iron strips to expand, ultimately resulting in the bending of the bimetallic strip, which on bending touches the screw adjacent to it, thus completing the circuit. Once the circuit is complete, the bell begins to ring. Thus the brass bends more than the steel, but on cooling, contracts more than the steel, thus causing the bimetallic strip to bend in the opposite direction.

How are bimetallic strips used in electric irons?
It is used as a thermostat.A thermostat is a device used to control the temperature of any equipment, in this case an electric iron.Two little strips of different types of metals are welded or brazed together. These little strips will be mounted inside the the iron near to the hot plate, held down just at one side.An electrical contact will join the bimetallic strip into the electrical circuit of the iron. Another little flat metal plate will be mounted near the free end of the bimettalic strip. This little fixed plate will touch the free enf of the bimetallic strip.So now you turn the iron on. The irons' hot plate heats up. The bimetallic plate heats up too as it is close to the hot plate.Ok, now is the clever bit someone once thought out. The two strips of metal heat up and expand. As the properties of the metals are different they will expand at different amounts. As the two strips are stuck together the bimetallic strip will bend.When it bends it will eventually bend away from the fixed plate. Assuming its been installed with the bimettaic strip the right way around! because the strip will bend to the side which has the metal that expands less. When it no longer touches the plate the circuit will turn off. And hence the power is turned off to the iron.So how come that dial makes the iron hotter or less hot? When you are twisting the dial you are actually squeezing some tension into the bimetallic strip so that it will have to get hotter before it will bend away from the contact and hence break the circuit.
Why is bimetallic stripes used in gadgets?
Bimetallic strips consists of two strips of fused together along their length. On one side, you'll see one metal; flip it around and you see another type. Since metals don't all expand and contract at the same rate, this bimetallic strip will be straight at only one temperature. Heat the strip up and the strip will bend because one metal will expand more than the other. This bending of the bimetallic strip is used in thermostats to regulate temperature. This strip provides a closed circuit to a heater. When it gets too hot, the strip bends and cuts off the electric current. No more heating goes on, and the strip starts to cool. When the bimetallic strip is straight again, the circuit is connected, and the heater heats up again.

How is a bimetallic strip used in a thermostat?
A bimetallic strip is used in a thermostat to control temperature. As the temperature changes, one of the metals expands or contracts more than the other, causing the strip to bend. This bending action either opens or closes a switch to turn the heating or cooling system on or off, helping to maintain a set temperature.
How is the bimetallic strip used in everyday life?
A bimetallic strip is commonly used in thermostats to regulate temperature. When the strip is heated, the two metals with different coefficients of expansion cause it to bend, which in turn triggers a switch to turn on/off a heating or cooling system. This mechanism is used in devices such as ovens, refrigerators, and kettles.
Why does a bimetallic strip curve when it is heated?
A bimetallic strip is made up of two different metals with different thermal expansion coefficients. When heated, one metal expands more than the other, causing the strip to bend due to the unequal expansion rates.
What uses bimetallic strip?
Appliances like electric iron, which need a cut off from the electric current from time to time as the appliance is heated adequately, use bimetallic strip for this.
