Strain gages A, B, C and D are mounted on a specimen subjected to a simple bending moment M and an axial load F, as shown below. Denote the bending strain, axial strain and thermal strain on the upper surface of the specimen as E, E and ET, respectively. i) Write down the expressions of the measured strains by each gage; ii) Is it possible to connect the four gages to a standard bridge so as to sense the bending strain only? If so, show all the possible full bridge connections and present the output of the full bridge circuits that meet the requirement. F F4 M A B A B C 00 D M C 59. D F
