A railroad tie (or sleeper) is subjected to two rail loads, each of magnitude P = 175 kN, acting as shown in the figure. 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. The distance L-1500 mm and the overhang length a - 500 mm. a) Draw Bending Moment diagram for the sleeper. b) Calculate the maximum bending stress ou, in the tie due to the loads P.
