Question

4) Design a vertical wall by providing adequate spacing of studs and wales and identifying which spacing governs between the bending, deflection, rolling shear. Also design for the maximum spacing of the ties and the bearing. (note you need more than 1 set of wales, they are to be spaced equally) Form grade plywood sheathing 3/4 inch. thick is available in 4x8 ft. sheets, and 4500-1b coil ties are on hand. Framing lumber of No. 2 Douglas Fir-Larch is to be used as required.
