* Example. — The greatest weight, uniformly loaded, upon a Red Pine joist 8 inches deep 
and 8 feet long, is 3 cwts. to the foot ; then if 6 times that weight be the breaking weight 
to the foot, the breadth of the joist should be 6 x 3 x •1250 = 2"25 inches. 
By Table II. page 128, the deflection of a joist 8 inches deep and 8 feet long, uniformly 
loaded with one-sixth of the breaking weight, is ^ x "263 = '21 of an inch.
