Gere & Goodno — Analysis of Stress and Strain: Problem 7.3-10

7.3-10 The normal and shear stresses acting on element B are \(\sigma_x = -46 \text{ MPa}\), \(\sigma_y = -13 \text{ MPa}\), and \(\tau_{xy} = 21 \text{ MPa}\) (see figure for Problem 7.2-10). Determine the maximum shear stresses and associated normal stresses and show them on a sketch of a properly oriented element.
