The maximum bending stress at a cross$-$section subjected to a moment M is given as $=$ M$/$S$,$ where S is Section Modulus. If for a rectangular cross$-$section of width b and height h the Section Modulus is given as S$=$ bh$2/6,$ what is the maximum bending stress at this cross$-$section if M$=60$kN$.$m$,$ b$=227$ mm$,$ and h$=319$ mm$?$ Express your answer in MPa using one $(1)$ digit after the decimal point
