- Torsion of
circular cross-sections is considered by the MDSolids software. Four different
torsion member options are available.
- The user can define a simple torsion
member (i.e., one shaft with one torque). This shaft is shown as a 3-dimensional
representation. A grid is superimposed on the shaft to illustrate the twisting
produced by a torque.
- Mohr's circle
calculations can be initiated from this torsion option. Standard values
for shear moduli are available to the user by simply clicking on the desired
material in a drop-down menu.
- Optionally,
an axial force can also be considered in the problem, and if the shaft is
a pipe shape, the effects of pressure can be included. This permits problems
with combined axial and torsion effects to be considered.

- Two torsion
options consider power transmission problems. One of these options considers
a single shaft connected to a motor while the second option considers a power
shaft connected by gears to an idler shaft.
- The power/idler
shaft option also includes an animated motor and gear movement with simulated
throttles so that users can observe the effects produced by changing motor
power, speed, or gearing ratio.

- Each of these
three options feature a flexible problem definition format. The user enters
the known variables and the software solves for the remaining variables.
- Extra explanations
describe in words the specific procedure that should be used to solve each
problem.

- A fourth torsion
option considers a single shaft with multiple torques. This option produces
a torque diagram, a shear stress diagram, and a twist angle diagram.

- The torsion module also includes two routines pertaining to statically indeterminate torsion assemblies:
- Torsion of coaxial shafts
- Torsion of end-to-end shafts
