[TowerTalk] Trylon

[David Gilbert]

I asked ChatGPT the question:

"how can I calculate the wind pressure in Pascals if I know the wind 
speed and surface area?"

It returned:

"Wind pressure can be calculated using the formula: P = 0.613 x V^2 x A, 
where P is the wind pressure in Pascals, V is the wind speed in meters 
per second, and A is the surface area in square meters. This formula 
assumes that the wind speed is measured at a height of 10 meters and 
that the wind is hitting a flat, smooth surface."

This AI stuff is interesting ... it's often quicker to ask the bot than 
it is to do a Google search.
