A bimetallic strip is used as a sensor. The strip has a length of 20 μm. The width of the strip is 1μm. It has an upper layer made of steel (E = 210 x 10 9 N/m 2 ) and the lower layer made of aluminum (E = 80 x 10 9 N/m 2 ). 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.
