Vertical Axis Wind Turbine Design and Installation at Chicamocha Canyon

The wind energy potential of the canyon is analyzed by using the mass conservation principle Eq. (1): dm dt = ρ ∗ A ∗ U E1. where ρ is the air density, U the velocity and A is the swept area. Then, the wind energy potential, P, can be expressed as kinetic energy per time unit as Eq. (2): P A = 1 2 ∗ ρ ∗ U 3 E2.

Mechanism of Earthquake Forces & Methods of Resisting Seismic and Wind ...

The more the ground moves, or the greater the weight of the building, the more force must be resisted by the building. When an architect or engineers designs a building, he or she must determine the maximum force a building might have to resist in the future. Buildings are always designed to handle normal vertical and lateral forces.
