    Learning Objectives

    On completion of this TLP package, you should:

    • Understand the stress distribution within beams subject to bending or torsion.
    • Be familiar with the concepts of the radius of curvature of a section of a beam (and its reciprocal, the curvature), second moment of area, polar moment of inertia, beam stiffness and torsional stiffness.
    • Be able to calculate the moments acting in a beam subject to bending or torsion.
    • Be able to calculate the deflections of a beam on bending and the angle of twist of a bar under torsion.
    • Be able to predict the effect of plastic deformation, at least with simple beam geometry.
