* Example. — A Red Pine joist 8 inches deep and 8 feet long, uniformly loaded with one- 
fourth of the breaking weight, deflects in the middle •263 of an inch ; the same joist uni- 
formly loaded with one-Jiflh of the breaking weight, deflects ^ x 263 = '210 of an inch ; with 
OM-sirth of the breaking weight, the deflection is 4 x "263 = '175 of an inch ; and so on.
