(4 points) The following figures represent two plates of different materials on the same subgrade (natural soil) subjected to the same vertical point load. 1. Plate 1 Plate 2 Steel Rubber Answer the following questions: a. Which plate is subjected to the lowest internal bending stress? b. Which plate results in the lowest maximum vertical stress in the subgrade? Which plate results in the highest maximum deflection (vertical deformation)? Which plate is most appropriate for field tests to determine subgrade modulus from deflection? Why? c. d.

Solution

a.plate2

b.plate2

c.plate2

d.plate1 because we dont find modulous of rubber accuretly
