$(4)$ Design the bending reinforcement for a rectangular concrete beam whose

breadth and effective depth are $400mm$ and $650mm$ respectively to resist

an ultimate Design moment of $700kNm.$ The characteristic strengths of the

concrete and steel reinforcement may be taken as $40\frac{N}{m}{m}^2$ and $500$

$\frac{N}{m}{m}^2.$

$(5)$ The Ultimate design moment to be resisted by the section shown $($breadth

and effective depth are $260mm$ and $440mm)$ is $185kNm.$ Determine the

Area of tension reinforcement $($As$)$ required, where $F_y=460\frac{N}{m}{m}^2$ and

$F_{cu}=30\frac{N}{m}{m}^2$

NOTE: draw all designed sections with all geometric properties
