39.
There are two hinged semicircular arches A, B and C of radii 5 m, 7.5 m and 10 m respectively and each carries a concentrated load W at their crowns. The horizontal thrust at their supports will be in the ratio of
1 : 1 1/2 : 2
2 : 1 1/2 : 1
1 : 1 : 2
none of these.
Answer: Option
Explanation:
No answer description is available. Let's discuss.

Doesn't depend upon the radius due to the concentrated load applied in a semicircular arch.

The Right answer is 1:1:1.

No @Prachi

The right answer is 1:1:1.

@Prachi.

That is for the parabolic arch, not semicircular.

Thank you @Prachi.

General equation of horizontal thrust for this condition will be;
H = Wl/4h.
h = l/2.
5/2.5:7.5/3.75:10/5.
= 1:1:2.

Three hinged arches h is independent of radius hence ratio must be 1:1:1.

1:1:1.
H=w/π.
H Not depend on radius.

Which is the correct answer? Please explain me.

Agree the given answer is wrong.

It doesn't depend on radius.

So, the answer is D.
