Torsion Members under Loading - - Click here for a Gear Train Application

Key Concepts: A torsion member, such as a rod subjected to a torque, will twist resulting

in a shear stress, shear strain, and rotational deformation.

In a Nutshell: A torsion member is generally long in axial direction (i.e the x-direction),

straight, and has a constant (or mildly tapered) cross-section. It may be subjected to one or

more torques and/or a distributed torque along its axis. The cross-section (generally circular

or near so) of the torsion member will have a centroid. The x-axis of the torsion member

is assumed to lie along the centroid of each cross-section. Click here to view a typical

torsion member.
