Question : 199 of 200

Marks: +1, -0

If a three-hinged parabolic arch, (span l, rise h) is carrying a uniformly distributed load w/unit length over the entire span,

horizontal thrust is (wl $^{2}$ )/8h
Shear Force will be zero throughout
Bending Moment will be zero throughout
All option are correct

Validate

Solution:

In three-hinged parabolic arch of span l and rise h is carrying a uniformly distributed load w/unit length over the entire span generates-Horizontal thrust = (wl

^ 2

)/8h
Shear force and BM in 3 hinged arch is zero
