or 4-41 by 2i, or 4-25 by 2|, or 4 by 3, or S SO by 3^, with 4'57 cwts. uniformly 
loaded, or 2'85 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 8 ft. long, 4-25 in. by 2i in. is 9-89 x 4-57 = 45-l c wts. 
uniformly loaded, or 7'91 x 2'85 = 22 o cwts. suspended from the middle.
