AI Thread Summary
The discussion centers on calculating the minimum radius of curvature a jet pilot can tolerate when pulling out of a vertical dive at 250 m/s, given that pilots can withstand about seven times their weight in g-forces. The formula v^2/R = 7g is suggested for solving the problem, emphasizing the importance of centripetal force. It is noted that with training and special suits, some pilots can endure up to 11 g's. Additionally, the Air Force evaluates candidates' genetic ability to handle g-forces before training. The conversation touches on extreme g-force experiences, with a mention of an individual who endured nearly 50 g's, resulting in severe physical consequences.

Here is a good one
The question reads
The max force a pilot can stand is about seven times his weight. What is the minimum radius of curvature that a jet plane's pilot, pulling out of a vertical dive, can tolerate at a speed of 250 m/s ?
Am I just crazy or is there not enuff info here to come up with a good answer.
Thanks tumbleweed

With training, and wearing an 'anti-g' suit, some pilots can withstand 11 'g' before passing out! (Hey, 7 'g' is good!)

In the Air Force, they now check applicants inherent genetic ability to withstand 'g' forces before training them up for the aircraft that pull 11 'g'. Only some people can ever cope with such stress.

Awesome!

..er What?
 
The largest g force anyone has voluntarily experienced was close to 50 g's. The persons retinas were detached. fun! :smile:
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
