Question

The figure shows a two-hinged parabolic arch of span L subjected to a uniformly distributed load of intensity q per unit length


The maximum bending moment in the arch is equal to

• A. $\frac{q{L}^2}{10}$
• B. $\text{Zero}$
• C. $\frac{q{L}^2}{8}$
• D. $\frac{q{L}^2}{12}$

Answer 1

The correct option is B $\text{Zero}$

If two-hinged parabolic is subjected to uniformly distributed load of intensity q per unit length, the bending moment at everywhere in the arch is zero. So Maximum bending moment in arch is equal to zero.
