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:

Answer is D because in this case horizontal trust is irrespective of radius of arch.

Snehal Wankhede said:   9 years ago
I think it is 1 : 1 : 1.

Amulya Rajbhar said:   9 years ago
Horizontal Trust of 2 Hinged Semicircular arch is independent of its Radius.

Horizontal Trust = W/pi.

Dibya said:   8 years ago
Yes, @Snehal.

It is 1 : 1 : 1.

Keshav raidas said:   8 years ago
H = W/π. So D is the right answer.

Apcivilian said:   8 years ago
Agree the given answer is wrong.

It doesn't depend on radius.

So, the answer is D.

1:1:1.
H=w/π.
H Not depend on radius.

Parvat kumar said:   6 years ago
Three hinged arches h is independent of radius hence ratio must be 1:1:1.

Prachi said:   6 years ago
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.
