Question

6. Let the components of the Cauchy stress tensor for an object B at time t be 0 CX3 T = [Tj] = | bx3 ax2 cx1 MPa, where b, c, and d are constants . - 0 -bx10 (a) Determine the body forces required if the object B is at rest for all times t. (b) At the location x - (4,7,-4), calculate the traction vector acting on the surface defined by -X1 + 2x2 + 2x3-2-0 and the surface defined byxf + +培-81-0.
