The horizontal deflection of a parabolic curved beam of span 10 m and rise 3 m when loaded with a uniformly distributed load $$l$$ t per horizontal length, is (where $${I_{\text{c}}}$$ is the M.I. at the crown, which varies as the slope of the arch).

The horizontal deflection of a parabolic curved beam of span 10 m and rise 3 m when loaded with a uniformly distributed load $$l$$ t per horizontal length, is (where $${I_{\text{c}}}$$ is the M.I. at the crown, which varies as the slope of the arch). Correct Answer $$\frac{{200}}{{{\text{E}}{I_{\text{c}}}}}$$
