are there any freely available programs/formulas written to calculate
load/stress/distribution (and any other factors) in theatrical and
entertainment rigging - using a programable (graphing) calculator such
as a sharp 9600.  ie: the closest I was able to find:

for other applications, rigging and truss loading is one application I
can see a graphing calculator to be useful, but also electrical
dimming loads and distribution tailored to theatrical and production
event lighting is another.
