1) Calculate the vertical induced stress (Ao) at point A in the two cases below. In both cases, the point A is 5 ft below the ground. The pressure induced by the foundation is 2560 lb/ft2 at the surface. 11.00 -11.00 5.00 5.00 8.00 8.00 A 3.00 3.00 5.00 5.00

In the figure, the rectangular foundation is loaded with a uniform load of 225 kPa. Accordingly, calculate the vertical stress increase 10 m below point A.

Cross sectional area and section modules of a short hollow Cl column section are 200 cm2 and 2x 10^6 mm3 respectively. It carries an axial load of 400 KN and a load of 100 KN on a bracket. The load line being 250 mm away from axis of column. Minimum and maximum stress intensities are respectively- 11:16 PM FF: 10:

A rectangular footing with dimensions of 8ft x 12ft is constructed at the surface of the ground and supports a column with a load of 192,000 lbs. The load applied to the footing results in a uniform stress distribution at the base of the footing. What is the change in vertical stress 12 feet below the ground, underneath Point A, at the corner, on the diagram?
