(b) A 45° strain gauge rosette is attached to the surface of a steel plate and under a particular loading case, the strain readings are as indicated in Figure Q3(b). Determine: i) the magnitude and nature of the principal strains, and the directions of the planes on which they act; ii) the magnitude and nature of the principal stresses. Data: For steel, E = 200 GN/m and v = 0.3. & = 100x104 En = 300x10 45 45 EA = 400x10
