9.3 Mohr’s Circle:

Section 9 – 5: Axial Load and Torsion:

Section 9-6: State of stress in a beam:

How does this compare to max normal stress at point P? How does this compare to absolute max normal stress in the beam??

9.6 Absolute Max Shear Stress:

• Key: Consider plane stress cases only if both stresses are positive, max shear stress is out of plane and given by:

2minmax

maxabs

Case 1 - Plane Stress

Max shear stress is out of plane!

Case 2 - Plane Stress:

Max shear stress is in plane!
