Wondering if any mechanical engineers out there could calculate this:  If you 
had 60 feet of 2 inch OD x .125 wall 6061-T6 (held solid at one end) how much 
rotational torque (foot pounds?)  at the other, free end would it take to twist 
the mast 3, 5 and 10 degrees respectively?

Working on something and don't want to find out too far into it that it won't 
work.  This is not a matter of whether something will fall or cause damage to 
anyone or anything - only loss of time and effort.

Thanks...Stan, K5GO
