9-4 A railroad tie (or sleeper) is subjected to two rail loads, each of magnitude P-200kN, acting as shown in the figure. The reaction q of the ballast is assumed to be uniformly distributed over the length of-a- the tie, which has cross-sectional dimensions b-200mm and h-120mm. Determine the deflection curve of the beam. 9-5 Derive the equations of the deflection curve for beam AB, with guided support at A and roller support at B, supporting a distributed load of maximum intensity qo acting on the right-hand half of the beam (see figure) 7o
