A Ng K 15 Mpa 99 A Long Rail Is Subjected To A Concentrated Load At Its Center Fig 9 2 Determine The Effect On 1 (156.83 KiB) Viewed 43 times

Please help me with this problem (9.9). I saw the book solution
already on answers but it wasn't very clear.
- a ng k = 15 MPa. 99. A long rail is subjected to a concentrated load at its center (Fig. 9.2). Determine the effect on maximum deflection and maximum stress of over- estimating the modulus of foundation k by (a) 25% and (b) 40%. 9.10. Calculate the maximum resultant bending moment and deflection in the rail of Prob 9 5 if two wheel loads spaced 1.66 m apart act on the rail. The
