A three hinged parabolic unsymmetrical arch has a span of 16 m carries an inclined concentrated load of 30+X kN as shown in Figure 5. Member BD carries a uniformly distributed load with a magnitude of 15 + Y kN/m. The arch is supported with pin support at both A and B and has the highest point of 5 m. Determine vertical and horizontal reactions at support A and B. (b) [10 Marks] Determine shear, normal and moment forces at point D and E (3m from support B).
