Hello. I need help with the following problem:

I don't know where to start. I know that the frame can be split up into one symmetric part and one symmetric+assymetric part but i forgot the theory and rules on translation and axis etc.
I hope someone can help as I have to hand in the assignment soon and my grade depends on it.

Best regards
Johnny
