Q.7.20 In a stressed member two strain gauges are fixed such that they are inclined at 30° to the known directions of the principal stresses. The strains measured in these two gauge are +445 x 10 and -32 x 10 •, 0 respectively. E = 2.1 x 10 N/mm? and Poisson's retio u = 0.3. Determine the magnitude of the 30 principal stress. + 446 + 10 lution: 30 -32 * 10
