Using suitable units, the stress at a particular point in a solid is found to be:

a.

b.

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.
