Hello Frans.
Who is pulling it. Gravity
It will move is an arc towards the ground.
A wing is similar to a sail on a sailing boat.
You can not sail directly into wind you can get to about 30 degrees of it.
Sorry Frans but at the moment i am still puzzled.
At the moment i am thinking this bar has three purposes,
1. to prevent the drag pulling the wing back, which is most of the time.
2. two provide the rigidity to the structure so keeping the front pin locked
into
its mounting.
3. to stop the wing coming "forwards" in abnormal wing loadings,
Possible very high A/A, near the stall, or gusts, or abnormal flight attitudes.
This puts this bar in compression , tension and neutral loads
But i am willing to change my mind,as i have used up ask a friend, may be its
time
to ask the audience,
Regards .
Alan
