For deflection calculations, the adjusted modulus of elasticity Ex’ for a hardwood glulam beam 16F-V4 with ASD load combination (D + 0.6W), over 16% moisture content, and a constant temperature of 140°F is _______.

A cardboard box that has been glued to the ground experiences pressures p1 = 0.85 psi and p2 = 1.05 psi on one side. The box has dimensions L1 = 16 in., L2 = 8 in., and h = 12 in. Use the pressure tributary to the diaphragm (lid) of the box to determine the reaction force V1 between the diaphragm and the shearwall (short side of the box).
