Which part of a straight wing stalls first

[hinhin]

Hey guys
I have come arcoss with the stalling of a st. Wing
.i have read in my textbook that st wing stalls at root first. Is it because the spanwise flow of the st wing flows towards to the root which gives rise to the above phenomenon?!

Also for the sweptback wing, as for the tips stall can I explain it as " the accumulation of spanwise flow at the tips has given rise to a lower energy boundary layer over the tip, and therefore stalls first before the root"

Thanks guys!

The inboard part, because of "washout": the wing is twisted so the tips have less AoA; they therefore stall last. It means as you start stalling, you retain roll control. This also feature also occurs on swept wings. Also, on a swept wing, if the tips stalled first, you'd get a pitchup (centre of lift effectively moved forward) which would completely ruin your day!

Phew!
Thanks for that, PDR.
So that's where I went wrong, eh?
I hadn't given much thought to how a dog-tooth and bat-tail might have helped on a Traumahawk.
Anyway, as it turned out, the aircraft was usable again.
Respect, bro.
