Re: How is the pressure at the center of a rubber-band ball be determined?

Hello Spencer

This looks like a tough question.  I am thinking that it can
only really be determined experimentally.  I do not know how tightly
you wound the rubber bands.  Over time they may lose some of their
spring constant and the force they exert may drop.  Pressure on the
outside of the ball will affect the center pressure.  This would include air
pressure and the deformation caused by gravity if the ball is sitting on a
surface.  It is also possible the rubber bands would have a spring constant
related to being bent which could reduce the center pressure.

You may want to re-introduce this question to Mad Scientist to get an answer
from someone who could suggest a mathmatical model.

Thanks

The Mad Scientists asked me to come up with an experimental method of 
measuring pressure at the center of the ball.  Unfortunately, I cannot 
think of a method that is not very expensive.

My apologies,
