[itex]q = \tau/b[/itex]
[itex]\tau = (VQ)/(Ib)[/itex]
I would like to calculate the shear flux in one row of nail. By taking the first moment for the upper board, calculating q and dividing by 2 I get the correct value.
My question is the following, why can't I take for example the left board? I would get Q=0, but what is the physical meaning of this? Why can't I use the left or right board to calculate the flux in the nails?
