So, for the past three days, my classmates and I have been working with Statics, and it has been going well, we were 3-5 dudes who chose to sit together in front of a whiteboard, and just crunch the different problems we were given, and we have gotten through them all, cross-referencing with a list of answers provided by our teacher, to see if we had got it correct, and this problem has been annoying since yesterday, all throughout today.
All the values we have been given, and for the most part we have gotten a hang of it, but there is just one number (and a rather essential one at that) that we can't place, that is the 45.1 in the equation (we looked at a previously turned in assignment, and have taken it from that, trying to work backwards, to see if we could make sense of it), attached to this post are the values that we have been given, we have found our Ix and Iy values in a Static book that we have been given.
If you know how to solve this, or know how to get the 45.1 somehow, please show us, this problem is really bugging us, we have probably spent close to 5-6 hours total on it.
Sincerely
J.P
