The formulas for rupture and deflection usually given are quite inconvenient in form, because large numbers must be used in computations, requiring the use of seven place logarithms or tedious arithmetical computations. By transforming these formulas, changing lengths from inches to feet, loads from pounds to tons, constants for the material from pounds to tons, and bending moments from inch-pounds to foot-tons, simplifying the resulting formulas as much as possible, they may be put into forms far more convenient for practical use, and *may then be grouped on a single page for each mode of support arid arrangement of the loading. These simplified formulas can be applied With sufficient accuracy by using a good slide rule or a four-place table of logarithms.
