| Definition of the shear centre | The point through which a transverse load produces bending without twist | Timoshenko SP, Gere JM, Mechanics of Materials |
| Symmetric sections | For sections with an axis of symmetry the shear centre lies on that axis | Timoshenko SP, Gere JM, Mechanics of Materials |
| Open thin-walled sections | For channel-like open sections the shear centre often lies outside the profile | Roark RJ, Young WC, Formulas for Stress and Strain, McGraw-Hill |
| Eccentric loading | A load offset by e from the shear centre induces a torque T = V · e | Roark RJ, Young WC, Formulas for Stress and Strain |
