The examples studied in this chapter show clearly the necessity for carefully determining the stability of the entire structure, as well as that of the roof. CHAPTER IX SAFE STRENGTH OF MATERIALS 431. Simplification of Formulas, Data, and Computations.--Long experience in the study and application of the formulas and data comprised in this chapter has clearly shown: 1. That the usual formulas for strength of materials may be put into simpler and more convenient forms for practical use. 2. That the necessary computations are greatly abbreviated by some changes in notation and coefficients. These improvements consist in taking the loads and coefficients of strength in net tons instead of in lbs.; bending moments in foottons instead of inch-lbs.; lengths in feet instead of inches, and distances between centres of beams and purlins in feet instead of inches. Sectional dimensions and distances between centres of rafters and joists are always taken in inches. 432. Notation Employed.--Let W = load in tons producing the stress. A = effective area of cross-section in square inches. P = stress in tons per square inch of cross-section. L = length of member or beam in feet. b = breadth of a recta...
