I need to know a realistic minimum biaxial tension per unit length - in N/m - for the surface of a membrane which is 27.4 mm square - with surface density 0.0912 kg/m^2 - so that it could be vertical and remain tense so that mode shapes due incoming acoustic energy would remain intact (if the membrane goes too limp, the mode shapes will become distorted).
Also, the membrane must be able to remain stretched when a small central mass of 1 g is attached.
A realistic value from a paper I'm following uses 486.4 N/m, and I'd like to know if it can go as low as 2 N/m.
Basically at what tension will it become unacceptably limp?
Many thanks
