Okay, I've got the support reactions at the top wing struts and shears and bending forces for the top wing.
But don't understand the following steps:::
[[ So, go back to the FBD of the upper wing and now sum moments about the strut attach point, as though the point were fixed.]]---I did the...
Help, help, help. Weather is great for flying and I'm sitting here tearing out my remaining hair trying to get a moment diagram constructed for my top wing. Just going in circles and have no one to check me (hint-hint-hint).
Let me defer answering your last helpful email and

Now that is a great reply!! Thanks.
Before I disappear for a couple of weeks now digesting this, let me shed a little more light on my efforts todate
