Given

The beam shown in the figure below is supported by two rods, $AB$ and $CD,$ which have diameters of $4\mathrm{.}12$ mm and $3\mathrm{.}00$ mm $,$ respectively. An applied point load of $32\mathrm{.}0$ kN is applied at a distance, $d=1\mathrm{.}00$ from $A.$

Required

Determine the normal $($tensile$)$ stress in rod $AB$ in MPa to the nearest $100$th$,$ i$.$e$.,$ two $(2)$ decimal places.
