Q. A strain gauge rosette that is attached to the surface of a stressed component gives 3 readings (ɛa = A, &b = B, &c = C). If the strain gauge rosette is of the Dº type (indicating the angle between each of the gauges), construct a Mohr's Strain Circle overleaf. You should assume that gauge A is aligned along the x-axis. Using the Mohr's Strain Circle calculate the: (i) principal strains (8₁, 82)? (ii) principal angles (1, 2)? You should measure these anticlockwise from the y-axis. (iii) maximum shear strain in the plane (ymax)?
