I've done this before, but I can't figure out what I've done wrong here. I have another sheet that I use regularly and it's set up very similar, but this one just won't Solve.

Any help would be appreciated.Trailer and Crush Energy.sm (18 КиБ) скачан 156 раз(а).

Okay. I feel really dumb. I mistook my "W" for my "w". Unit analysis saves the day.

I'm still having issues though. After fixing the above issue, I need to force the positive solutions. I'm not sure how to do this. The positive solutions verify the test data I have.

That's great. Thank you very much. I've got it up and working, but I'm having a disconnect on my units. The answers are correct as per my hand calcs, but they don't come out with units attached. If I click in and just add my units, it converts to the correct number, but the units are not correct. I went through and did a unit analysis, and I can't find anything wrong. Also the answers and units come out correct when I used Solve and Assign.
