The truss in Fig. 7.B supports the roof dead load of 16 psf shown in the sketch. Trusses are spaced 24 in o.c., and the roof live load is to be in accordance with the IBC. Lumber is No. 2 DF-L. Fasteners do not reduce the area of the members. Truss joints are assumed to be pin-connected. CM = 1.0, C₂ = 1.0, and C; = 1.0. Find: a. The required member size for the tension (bottom) chord using ASD.
