the torsional constant and the approximate equation he sent is what I was
looking for and what I also found after some searching through my storage in
the garage. It was also in my older Salmon and Johnson text.
Thanks

Dear,
"J" is the polar moment of inertia.
It is the square root of summation of square of moment of inertia
about "x-axis" and "y-axis".
You can find it in any standard Handbook.
