A rectangular bar with a simple beam of $6\mathrm{.}0$ m between $12$ kN$/$m of the beam and $60$ kN of the concentrated load in the center of the beamDesign a section of the shape. Calculate the required section and the amount of reinforcement. It is fck$=27$MPa, fy$=350$MPa.However, design the cross section at a ratio of h$/$b $=1\mathrm{.}5$ to $2\mathrm{.}5$ with the amount of reinforcement corresponding to t $=0\mathrm{.}005$
