Oh, foolish me... I was stuck at the T + G - B = 0 with no hope of getting rid of V or A... had I only started with the moments. Thanks, I think it makes sense now, I'll try it and see if I get the answer. E: Yes, I got the answer, thank you. I think the angle is a matter of geometry.

L = length of plank the angle θ between the forces and the moment arm is the same for both as the forces are only antiparallel. B = ρwaterVsubmergedg G = ρplankVplankg V = ? τB = rBsinθ = (L/2 - x) * ρwaterVsubmergedg sinθ τG = rGsinθ = (L/2) * ρplankVplankg sinθ (L/2 - x) * ρwVsubg sinθ =...

I would really like to have a solution given, or at least all the steps necessary, because I've been fighting with this for a good while and I don't feel like anymore, as it's not the only thing I need to know for Wednesday. If nobody gives me the answer before tomorrow, I might try it then...

Hello, I'm new and quite unfamiliar with all the conventions, but I'll use underline for vectors since I couldn't find the proper thing (is the convention to use bold here?) Problem: No more.Relevant equations: Fnet = ma = 0 τnet = Iα = 0 τ = r x F = rFsinθ Fbuoyancy = ρwaterVgAttempt at...
