1. The problem statement, all variables and given/known data A Cessna C-172M has empty weight 1350 lbs. When it is weighed, the load on each of the main wheels is 474 lbs. The load on the nose wheel is 402 lbs. Where is the center of gravity of the empty Cessna? Ok so the question assumes you know what a Cessna looks like, but it's like this: the nose wheel bears 402 lbs. The main wheels bear 948lbs (2 wheels so 474 x 2 = 948). 948 + 402 = 1350, so it's correct. 2. Relevant equations I believe this is the equation for translating 2 weights into 1 weight (the center of gravity being the 1 weight) L1 = (L x W2) / W L2 = (L x W1) / W 3. The attempt at a solution I apologize, but this is really confusing me. The reason I'm struggling is that I don't have any lengths, which I guess might mean that this is a 2 stage problem, but I can't seem to figure out how to even get started. If you look at my recent posts, you can see me working through similar problems, but this one is really throwing a curve at me. I keep solving until L1 = 948 / 1350 and L2 = 402 / 1350 but from here (even if this a correct first step), I have no clue how to go. Feedback would be really appreciated because I've been staring at this for over an hour (sadly).
