A steel strut shown below is rectangular in cross-section and is the part of the operating mechanism of a bascule bridge. The compressive load to be carried is \( 150 \mathrm{kN} \). Determine the required dimensions \( w \) and \( t \), assuming a factor of safety of 4 . The material has \( S_{y}=430 \mathrm{Mpa} \) and \( \mathrm{S}_{\mathrm{ut}}=570 \mathrm{MPa} \).
