Dear Group,

Dear Group,

I am developing a light weight product that will be hanging outside
and wanted to ask your collective wisdom about wind effects on it's
shape. It is approximately 30 (28 on shorter surface) x 40 x 2
inches. It has a symmetrical shape (with respect to leading and
trailing edges), basically a trapezoid (kind of like a stackable bin).
It will look something like this character picture if it comes out
correctly on your browser and font.

I am trying to anticipate or design how this thing will move in the
wind. The wind would be coming perpendicular to the 2 inch width,
that is, parallel to the flat top and bottom of the trapezoid. I want
it to not flap around so I am trying to create a shape that will force
it to flap backward (in the direction of the shorter surface) in a
wind and more or less stay there.

Any opinions?

Thanks in advance.
