3.2.6.4 Mast with three braces
For a mast with three braces consider the following dimensions when you design the mast
and braces:
• Mast length
• Mast outer diameter
• Connection point where the brace join the mast.
• Brace outer diameter
The shorter the braces become the more support they add to the mast. The 30 - 40 degrees
between the braces and the mast should be respected.
