The discussion centers on whether the pressure throughout an inflated fluid pad is uniform. It concludes that pressure will equalize once the weight is stable, indicating that points X and Y will have the same pressure. Participants agree that the answer is A, confirming uniform pressure distribution. The concept of equilibrium is emphasized as crucial to understanding pressure in this context. Overall, the pressure in the fluid pad is consistent once stability is achieved.

Homework Statement
Adding weight on an inflated air pad, does the pressure on any point of the pad would be the same?
Relevant Equations
P=F/A

I guess the pressure would reach equilibrium after the weight is stable, that is when points X and Y are stable. So, the answer should be A?

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
