A cardboard box that has been glued to the ground experiences pressures p1 = 0.20 psi and p2 = 1.00 psi on one side. The box has dimensions L1 = 15 in., L2 = 7 in., and h = 11 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).
