As one side expands more than the other, the strip bends. The amount of bending will be very large for even a small amount of expansion. The bending metal can pull a lever, that moves an indicator over a temperature scale. Thermometers using bimetallic strips are used in oven thermometers and in old thermostats.
Bimetallic strip bend in the presence of the heat and completes the circuit. This completion of the circuit sets the alarm on in case there is a fire. A bimetallic strip curvature equation was adopted to predict the self-folding of the prepared bi-layered hydrogel.

Beach house liftsBimetallic Element thermostats use a bimetallic fused together, typically into a coil shape. As the fused metal strip/coil is exposed to different room air temperatures, because the two metals expand or contract at different rates but are fused together, the spring "coils" or "un-coils", causing In Equation (7), there are two temperature variations, namely, ΔT bimetal and ΔT FBG due to the heat transfer loss between the FBG and the bimetallic sheet. Therefore, the value of Δ T bimetal is not the same as Δ T FBG although the heat is generated from the same source.

Nov 02, 2020 · Disciplinary Core Ideas: 2 MS-PS1.A3: Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. MS-PS3.A4: The term “heat” as used in everyday language refers both to thermal energy (the motion of atoms or molecules within a substance) and the transfer of that thermal energy from one object to another.
Stripe hackerrankDec 16, 2019 · The length of the strips after heating becomes, lC = l0(1+αCΔT), lB = l0(1+αBΔT). l C = l 0 ( 1 + α C Δ T), l B = l 0 ( 1 + α B Δ T). The strips bend as shown in the figure. From figure, the length of the two strips are lC = Rθ, lB = (R+d)θ. l C = R θ, l B = ( R + d) θ. Couplings comprising a chain or strip surrounding two wheels arranged side by side and provided with teeth or the equivalent [2013-01] F16D 3/56 comprising elastic metal lamellae, elastic rods, or the like, e.g. arranged radially or parallel to the axis, the members being shear-loaded collectively by the total load [2017-08] Figure 4-46. - Various types of bimetallic strips. corrosive to brass. When the temperature around the bellows increases, the heat gasifies the liquid inside and causes the bellows to extend. The extension closes a set of electrical contacts, as shown in figure 4-47, view B. When the bellows cools again, it contracts. I'm assuming this is independent of the model results. I get that once you have either d or the R, you can obtain the other using the equation in your pic, but I'm not sure I follow how one of them is obtained? If I used the bimetallic beam equation I linked above, I get R=101.67, which means d=0.97. I can't trust my hand calc since it's so far ...
