1. A steel railroad track is supported on timber sleepers, which exert on the track an upward force 2800 N per meter length of the track per mm of track deflection. For the track, the moment of inertia = 12 x 10 mm and the section modulus - 16 x 10 mm. A point load of 100 kN acts on the railroad at the midpoint. a) Determine the zone along the length of the track over which the track deflection is zero. b) Determine the maximum bending stress acting on the track. The modulus of elasticity of steel205 GPa..
