Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 740 psi in size.
(a) Determine the stresses ox, Oy, and the magnitude of Tyyand show them on a stress element.
(b) Determine the principal stresses and the magnitude of the maximum in-plane shear stress acting at the point and show these
stresses on an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16).
Answer:
(a) oy=
psi
Oy =
psi
Ty =
psi
(b) Op1=
psi
Op2 =
psi
Tmax in-plane =
psi
