A bimetallic strip of yellow brass and Monel 400 is bonded at 120?F. The thickness of the yellow brass is 0.014 ± 0.0002 in, and the thickness of the Monel is 0.010 ± 0.0001 in. The length of the strip is 5 in. Calculate the deflection sensitivity defined as the deflection per degree Fahrenheit temperature difference. Estimate the uncertainty in this deflection sensitivity.
