Physics · Structural Analysis - Arches
A three-hinged parabolic arch of span L and rise h carries a uniformly distributed load (UDL) of w kN/m over the entire span. At any cross-section of the arch:
- 1both the bending moment and radial shear force are non-zero.
- 2both the bending moment and radial shear force are zero.✓
- 3the shear force alone is zero.
- 4the bending moment alone is zero.
Correct answer
both the bending moment and radial shear force are zero.
