This table is inserted to be used in a more specific way than Table I, in cases of uniform loading where the total live load in tons uniformly distributed along the beam or girder is known, as well as the span in feet. Only a sufficient number of sizes are here given to cover the ordinary loading met with in practice, and such sizes are selected as are capable of withstanding the severest loading for a given amount of material--in other...
