The strain rosette shown in the figure was used to obtain the following normal strain data at a point on the free surface of a machine component: εa = 768 με, εb = 1210 με, and εc = 1320 με. The elastic modulus is E = 28,000 ksi, and Poisson’s ratio for the material is ν = 0.12. Determine the strain component εy at the point.
