1: A square footing is to be constructed as
shown in the Figure at a founding depth of 2 m. Using the
Terzaghi equation compute the ultimate surface capacity,
[ (qult)Surf ],
possible for the layered soil profile shown. Keeping in mind that
Terzaghi’s semi-empirical bearing capacity
equation can only be applied to a soil layer with a thickness
greater than or equal to the applied stress contact-area-breadth
(either virtual or real breadth). In such a case, second layer
cannot...

The helicopter shown in the figure below has a mass of 12 tons
and it needs to rotate its 14 meter blades (diameter of the blades
= 14 meters) at 670 rpm just to hover (stand still in mid air)
without any additional load. The air flow caused by the rotation of
the helicopter blades may be modeled as a moving cylindrical body
of air having a 14 meter diameter. The average velocity of the
airflow of that cylindrical air-body...

Two concentric spheres are shown in the figure below. The inner sphere is a solid conductor and carries a charge of +5.00 μC uniformly distributed over its outer surface. The outer sphere is a conducting shell that carries a net charge of -8.00 μC. No other charges are present. The radii shown in the figure have the values R1 = 10.0cm, R2 = 20.0cm, and R3 = 30.0 cm.
