The strain rosette shown was used to measure the normal strains at a point on the free surface of an aluminum (E = 10,600 ksi and v = 0.33, Poisson's Ratio) member. The measured strains were &₁ = +875 µ in./in., ε₁ = +700 μ in./in. and &c = -350 μ in./in. Gage b y 135° Gage a 90° X Gage c 135° a. Determine the principal strains and the in-plane maximum shearing strain at the point. b. Determine the stress components σx, σy and Txy. c. Determine the principal stresses and the maximum shear stress using the results of Part (a). Verify using the results of Part (b).
