Load moves along the three-hinged, parabolic arch \(A B C\), shown in Figure P12.24.

Construct the influence lines for the reactions at \(C\), and shear, axial load and moment at point \(D\). The equation for the parabolic arch is \(y=4 h x_{2} / L_{2}\). If a point load \(P=3\) kips is applied at \(B\), compute shear, axial load and moment at \(D\).
