1. Compute the reactions at supports A and E of the three-hinged parabolic arch in Figure P6.23. Next compute the shear, axial load, and moment at points B and D, located at the quarter points.

2. The three-hinged parabolic arch in Figure P6.24 supports 60-kip load at the quarter points. Determine the shear, axial load, and moment on sections an infinitesimal distance to the left and right of the loads. The equation for the arch axis is y = 4hx2 /L2
