How could a bimetallic strip perform a practical task in life?

bimetal stip is next to the contacts it make your oven,iron and air conditions unit work that is when ever the contacts touch from how high you put it and it heat up and the iron and brass bends

∙ 13y agoBimetallic strips can be used as thermostats.
The two metals expand at different rates, therefore, the strip will bend or curve. This property can be used to regulate the temperature of an oven. As the temperature increases, the metal bimetallic strip curves away and breaks the electrical contact, the oven cools. As the oven cools the strip straightens and the electrical contact is remade and the oven reheats.

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 the bimetallic strip in an electric iron do?
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 bimetallic strip. This little fixed plate will touch the free end 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 bimetallic 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.Thats the idea!
Any 5 gadgets in which bimetallic strip is used?
They're all thermostats of on kind or another: home, car, stove, hot-water heater,
What is a bimetallic coin?
A bimetallic strip is often used in thermostats because it is quite simple to make and responds predictably to changes in temperature. The bimetallic strip is pretty much what it sounds like - a strip made from two metals. Inthermostatsit is common to make one side out of steel and the other out of copper - then bond them together. they are formed into a curving spiral. Different metals have different coefficients of thermal expansion so as the temperature changes, the spiral strip either curls up or uncurls as one side expands or contracts more than the other. The control isattachedto one end of the strip so that as it curls or uncurls, it rotates the control.Sometimes the control is a simple mercury switch that closes a contact whenrotatedone way and opens the contact when rotated the other. Sometimes one end is attached to a power source and the other end is connected to an electric contact, which moves as the strip curls and uncurls.You can also attach it to a pointer and have it point to temperatures on a dial.
What is different about the two kinds of metal on the bimetallic strip of a thermostat coil?
the two dissimillar metals have different heat coefficient.on the application of heat the two mtels which are comonly bonded in shape of spiral or helix expands unevenly.that's results in diferential expansion that's unwind the expansion this differential expansion is sensed by the pointer and the differentail exapansion of the metal is shown in terms of pointer deflection on the scale as measured value............. the two dissimillar metals have different heat coefficient.on the application of heat the two mtels which are comonly bonded in shape of spiral or helix expands unevenly.that's results in diferential expansion that's unwind the expansion this differential expansion is sensed by the pointer and the differentail exapansion of the metal is shown in terms of pointer deflection on the scale as measured value.............
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
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.
What is the Operating principle of a bimetallic strip?
A bimetallic strip is used to convert a temperature change into mechanical displacement.
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.
