1. Compute the vertical displacement of the hinge at C in Figure P7.25. EI is constant.
2. The loading acting on a column that supports a stair and exterior veneer is shown in Figure P7.26. Determine the required moment of inertia for the column such that the maximum lateral deflection does not exceed 1 ⁄4 in., a criterion set by the veneer manufacturer. Use E = 29,000 kips/in.2.
