Section 1.3: Stresses in the Members of a Structure - More information that just the internal force (i.e. F BC = 30N) must be found to see if the material is sufficient to hold a load. We also must investigate cross-sectional area of a rod (or other support) and its material o F BC actually represents the resultant of elementary forces distributed over the entire cross-sectional area, A, and the intensity of these distributed forces is equal to the force per unit, F
