Hi again, Theresa -- since the 2nd beam is fatter and shorter, we can expect GREATER load support ... width bigger 9/4x ... ht bigger 4/3x ... h^2 bigger 16/9x ... L smaller 13/17 => bigger load by 17/13 ... expect bigger load of 9/4(16/9)17/13 ... 4(17/13) ... 68/13 ...

5 1/4x

**==> 52.5 tons :)**
