A rectangular singly reinforced concrete beam has a width of $300 \text{ mm}$ and an effective depth of $550 \text{ mm}.$ The grades of steel and concrete are Fe$500$ and M$25$, respectively. The area of steel in tension is $1963 \mathrm{~mm}^{2}$. The depth of neutral axis is $302 \text{ mm}.$ The ratio of the limiting depth of the neutral axis $\left(x_{u, \max }\right)$ to the effective depth ($d$) of the beam is $0.456$.
The most probable mode of failure of the beam is
- compression failure
- bond failure
- shear failure
- ductile failure
