Question
Calculate the principal strain.
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 @ respectively. E = 2.1 x 105 N/mm² and Poisson's ratio μ # 0.3. 30° -445 - 10
