Please can you help me with this problem? 

A railroad tie (or sleeper) is subjected to two rail loads, each of magnitude P= 175 kN, acting as
shown.
The reaction q of the ballast is assumed to be uniformly distributed over the length
of the tie, which has cross-sectional dimensions b = 300 mm and h = 250 mm. Calculate the
maximum bending stress Omax in the tie due to the loads P, assuming the distance L = 1500mm and
the overhang length a = 500 mm.
