Repeat Prob. 7.6 except that in addition there is a ceiling dead load applied to the bottom chord of 8 psf (16 lb/ft). Neglect deflection. Prob. 7.6 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 UBC Table 16-C, Method 1. 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, Ct = 1.0, and Ci = 1.0. Find: The required member size for the tension (bottom) chord.

Repeat Prob. 7.6 except that in addition there is a ceiling dead load applied to the bottom chord of 8 psf (16 lb/ft). Neglect deflection.
Prob. 7.6
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 UBC Table 16-C, Method 1. 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, Ct = 1.0, and Ci = 1.0. Find: The required member size for the tension (bottom) chord.
