A mysterious force has been discovered in nature that acts on all particles in the three-dimensional space. You determine that the force is always pointed away from a definite point in space, which we can call the force center. The magnitude of the force turns out to be proportional to 1/r4, where r is the distance from the force center to any other point. Your friend says that it has been determined that the constant of proportionality has been determined to be 2 (in units to be determined), i. e. the magnitude of the force on a particle can be written as 2/r4, when the particle is at a distance r from the force center.

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
