A railroad tie (or sleeper) is subjected to two rail loads, each of magnitude P = 196 kN, acting as shown in the figure. The reaction g 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 oy (in MPa) in the tie due to the loads P, assuming the distance L = 1,500 mm and the overhang length a = 510 mm. (Enter the magnitude.) MPa

Solid Mechanics

Engineering mechanics is a branch of science that deals with forces causing bulk motion in bodies and the effect that these forces cause on the bodies. Engineering mechanics does not deal with the internal changes that occur on account of these external forces. The internal effects in a body or a material under the action of external forces are studied in a new branch of science called solid mechanics, the strength of materials, or the mechanical behavior of engineering materials.
