Australian Fireball Mast Bend Tests

The following mail has been received from Australia:

Hi all,

Last Sunday a group of us performed end tests on a selection of masts - (too much spare time?)

We tested 8 masts:

  • 1995 Stratus
  • 2005 Stratus
  • 2002 Cumulus
  • old but unused Super spar M7 (#2 on sheet)
  • 2 x new M7+
  • Epsilon
  • Alto

The masts were supported at the heel and at the top black band with 15 kg weight attached at spreader height. 

Measurements were taken at 1 metre intervals beginning from the tip as well as a measurement at the spreaders.

We tested both fore and aft bend as well as sideways bend (both port and starboard - and yes there is a difference!)

The results are attached.

It was an interesting exercise with a few surprising results. It will be good to build up a database of mast types.

Thanks to Ben, Nathan, John, & Brett (I didn't do much) and especially Jack Fletcher for compiling all the results.

Robin.
