For the semi-circular, three-hinged arch \(A B C\), shown in Figure P12.23, construct the influence lines for reactions at \(A\) and \(C\), and shear, axial load and moment at \(F\). A uniform live load of \(2 \mathrm{kips} / \mathrm{ft}\) is applied along the top deck girder \(D E\), assume that the load acts uniformly on the arch through the vertical struts. Compute the reactions at \(A\) and \(C\), and shear, axial load and moment at \(F\) using the influence lines.
