Question

A 2-hinged semi-circular arch of radius 10 m carries a load system as shown in figure. The horizontal thrust at each support will be _____ kN.

• A. 84.35

Answer 1

The correct option is A 84.35

$H=\frac{120}{\pi }\times {\sin }^{2}30{}^{\circ }+\frac{100}{\pi }\times {\sin }^{2}90{}^{\circ }+\frac{180}{\pi }\times {\sin }^{2}60{}^{\circ }$

$H=84.35kN$
