Using this information, you can select a wine refrigerator that most suits your needs. We also considered the type of cooling technology used and features designed to help protect your wine, such as light-protected, insulated glass doors. The best wine coolers protect your wine from temperature fluctuations and light.
The length-to-width ratio is calculated by dividing the length of the marquise by the width. (Example) Oval length equals 6 millimeters; oval width equals 4 millimeters; 6 millimeters divided by 4 millimeters equals a length-to-width ratio of 1.5 to 1. Diamonds are rarely cut to a perfect 1.5 to 1 ratio.
Poisson's ratio is. 1  the ratio of the relative contraction strain (or transverse strain) normal to the applied load-to the relative extension strain (or axial strain) in the direction of the applied load.hen a material is stretched in one direction it tends to get thinner in the other two directions. Î¼ = - Îµt / Îµl (1) where Î¼ = Poisson's ratio Îµt = transverse strain Îµl = longitudinal or axial strain.
