 Torsion of
circular crosssections 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 3dimensional
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 dropdown 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 endtoend shafts
