18 | Torsional Deformation & Stress

At the end of this section you should be able to:

  1. Identify relevant material properties for torsional properties and find them on a table

  2. Solve for deformations and stress in problems with purely torsional loading for

    • Statically-determinate problems

    • Statically-indeterminate problems

  3. Estimate maximum shear stress in object with abrupt geometry change using stress concentrator equation and plots

Statically Determinate

Hibbeler 9e 5.53: Statically-determinate rod with multiple torques

Statically Indeterminate

Hibbeler 9e 5.82: Statically-indeterminate rod with multiple materials

Stress Concentrations

Hibbeler 9e 5.125: Shaft with fillet
