A bimetallic strip is used as a sensor. The strip has a length of 20 um. The width of the strip is 1um. It has an upper layer made of steel (E = 210 x 10° N/m³) and the lower layer made of aluminum (E = 80 x 10° N/m?). Each layer is 0.1 µm thick. Determine the equivalent stiffness of the strip in the axial direction. Note that the strips are perfectly attached. 20 μm I um f0.2 um Each layer is 0.1 jum thick
