Q- On the surface of a thick layered clay soil deposit, a point load of 750 kN is applied at a depth of 3.5m and a radial distance of 1.2m from the point of application of load. What is the value of the vertical stress using the Boussinesq's elastic analysis?

In a zone with a constant stress gradient of a mechanical- structural element, the stresses acting in the "x" direction are Ox = 5900 psi and Txy = 1950 psi. Determine the allowable values if the maximum shear stress is limited to Tmax = 2500 psi. for Ty

1. Find the stress increase 8 ft below point A in the drawing below. The applied surface stress is 4000 psf. 50 ft 30 ft A 50 ft 25 ft

8) Answer the ff: a) If the magnitude of the two loads is combined as one, what is the horizontal distance of the said load given that point A is at the same depth and that it experiences the same vertical stress increase given by the set-up? b) The stress contributed by q1 is: c) The total increase in vertical stress is: d) The stress contributed by q2 is: e) What is the equivalent horizontal load if it is located 3 meters away from point A given that the said point experiences the same vertical stress increase given by the set-up? Note: Point A is at the same depth
