Determine the spherical and deviatoric stress tensors for the stress states given in Exercise 3.2.

Data from exercise 3.2

Using suitable units, the stress at a particular point in a solid is found to be. Determine the traction vector on a surface with unit normal (cos θ sin θ, 0), where θ is a general angle in the range 0 ≤θ≤ π. Plot the variation of the magnitude of the traction vector ΙTⁿΙ as a function of θ.
