Can poisson's ratio be greater than 1
WebMar 30, 2016 · For a continuous random variable, the necessary condition is that ∫ R f ( x) d x = 1. Since an integral behaves differently than a sum, it's possible that f ( x) > 1 on a small interval (but the length of this interval shall not exceed 1).

WebIf the debt-to-assets ratio is greater than 0.50, then the debt-to-equity ratio must be less than 1.0. Long-term creditors would prefer the times-interest-earned ratio be 1.4 rather than 1.5. The assets-to-equity ratio can be computed as 1 plus the debt-to-equity This problem has been solved! WebThe PoissonÕs ratio of transformed foam was about 1.1 at small tensile strain, increasing to around 1.5 at a strain of 0.04, then decreasing to about 0.6 at large strain. 2.
