I like the idea of testing a airframe for strength before actually
commiting the beast to the air. Does anyone know how to calculate
the forces involved and where on the airframe to apply these forces?
Obviously(?) a 3lb plane pulling 4G will have to sustain a force
of 12lb, but where on the plane do I hang the appropriate number
of bags of sugar and where do I suspend the airframe from?
tta,
Keith.

Don't know the details but in most cases the inner third of the
wing usually carries 90% of the stress.

| 540.2 | What about the tail? | RDGENG::NODDLE | Keith Noddle - CSSE, Reading, UK | Fri May 13 1988 08:52 | 8 |
Thanks Tom.
That obviously indicates that I don't suspend the 'plane by the
wing tips! What about the force on the fuselage between wing and
tailplane - after all, the tails must generate some lift and therefore
put the fuselage under lateral strain...

Keith,
The April 1987 issue of Model Aviation has an article that
talks to G force calculations, etc...
If you don't have it, send me mail and I'll copy the article.
Hope this helps,
Brian
