8.18 Two planes AB and BC in an elastic material under load are inclined at 45° to each other. The loading on the material is such that the stresses on these planes are as follows: 1. on AB, 150 MN/m2 direct stress and 120 MN/m2 shear. 2. on BC, 80 MN/m2 shear and a direct stress o. Determine the value of the unknown stress o on BC and hence determine the principal stresses which exist in the material. [190, 214, - 74 MN/m²]
