The horizontal thrust equals wl² divided by 8hShear force remains zero along the entire archBending moment is zero at all points throughout the archAll of the above statements are correctNone of the above

Explanation

In a three-hinged parabolic arch under a uniformly distributed load, the horizontal thrust is given by wl²/8h. Additionally, both the shear force and bending moment are zero throughout the arch. Therefore, all the listed statements are accurate.
