Are there any guidelines for sizing masts and wall-thickness based upon 
how long and how much weight will be put on them?

I've got a Mosley CL-33M (42 lbs. 6.0 sq. ft.), and a Cushcraft A50-5S 
(11 lbs. 2.9 sq. ft.) I'll be putting on a 50ft. tower this summer.  I'd 
like to determine what sort of steel mast to use.  I'm figuring about a 
15ft to 16ft. mast with the CL-33M 1 ft. above the tower and the A50-5S 
near the top of the mast.

I'm not afraid to use a formula to size the mast.  In fact, that's part 
of the fun!
