[TowerTalk] Mast calculation

[Stan Stockton]

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
