2 Analysis of Stress
Determine the body force distributions at the point (3,
π
3
, 5) for the body to be
in equilibrium.
19. The state of stress at a point in a body is specified by the following stress
components:
σ x = 110 MPa τ xy = 60 MPa
σ y = −86 MPa τ yz = τ zx = 0
σ z = 55 MPa
Determine the principal stresses, direction cosines of the principal stress
directions and the maximum shearing stress.
