A semi-circular two hinged arch is proposed in a forest area for providing crossing (of river) facility for animals. And it is subjected to a maximum temperature change of . Take flexural Rigidity of arch material as 25000units. Coefficient of thermal expansion is . Due to change of plans it is converted to a parabolic shape with same overall geometry. For the same temperature change, what will be the percentage change in Horizontal thrust due to change of plans?
