How are multi-part equations best handled? For example, take the torsion equation:
We could express part of this equation like this:
torque := stress * moment / radius;
but then we could not re-define "torque" to mean something different in terms of G because it is already defined.
Ideally, we would like to represent the whole expression somehow and then solve for the term wanted depending on the situation. Is there any way to do this?
