The strain rosette shown was used to obtain normal strain data at a point on the free surface of a machine component. Given the values e, -165 μe, es= 155 μe, e = 50 μe, E = 10,600 ksi, and v=0.33, determine (a) the stress components a,,a,, and ry at the point. (b) the principal stresses and the maximum in-plane shear stress at the point; on paper, show these stresses on an appropriate sketch that indicates the orientation of the principal planes and the planes of maximum in-plane shear stress. (c) the magnitude of the absolute maximum shear stress at the point.
