The tower rests on the ground with an area of 450m² and exerts a pressure of 200 kPa. Determine the weight of the tower.

The ground pressure of the tower is equal to its weight divided by the area of the tower base. Therefore, the weight of the tower is equal to the pressure times the area of the base. That is

P = 200 * 450 = 90,000 kN.

Answer: 90,000 kN.
