Chapter 2: System Hardware
Wind blowing on the device will subject the mounting structure to significant lateral force. The
magnitude of the force depends on both wind strength and the surface area of the device. Wind loading
is estimated using the following formulae:
Force (in kilograms) = 0.1045aV
2
the surface area in square meters
wind speed in meters per second
Force (in pounds) = 0.0042Av
2
the surface area in square feet
wind speed in miles per hour
Applying these formulae to the ePMP device at different wind speeds, the resulting wind loadings are
shown in Table 18 and Table 19.
