04/27/2005: "Vivat-egad!"

Quite possibly the worst Vivato Install I've Seen.

The naked panel weights 42lbs. The observation deck is some 1100 feet above ground level. Wind gusts of over 60mph are common on top of the tower. The naked panel has an area of 1/2 square meter, or 5.8 square feet.

F= ((Vg^2)(A))/390

where:
F= Horizontal force, in pounds.
Vg = Wind velocity in mph.
A = Surface area, in ft2

A 60mph gust will generate 53 pound of force at the top of that mast. An 80mph gust will generate almost 100lbs of force. Thank God for the saftey fence.
