Re: Mass = Stress resistance?

Assuming that the living T. rex would have had a specific gravity (density as compared to water)
By coincidence. Water happens to approach 1 g/cm³ = kg/l.
between 8.5 and 1.00,
AFAIK baby birds (hardly pneumatized) have 8.5, while adult birds have 8.0. Something between these values might be more accurate for tyrannosaurs and produce a lower weight estimate and higher strength indicator.
They found the T. rex femur claimed a strength indicator of 7.5 to 9 m2/giganewton.
not GN/m², which would be a pressure, while the inverse sounds strange?
Does anyone know the strength indicator of an elephant?
