If you mean ratio then I don't quite understand the question.. but if you mean RADIUS Then you take the diameter and divide it by two. ============================================== There's no such thing as the ratio of circles. You can find the ratio of their diameters, the ratio of their radiussesses, and the ratio of their areas. -- The ratio of their diameters is: One diameter divided by the other one. -- The ratio of their radiusses is the same number as the ratio of their diameters. -- The ratio of their areas is the square of that same number.
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
The answer depends on whether or not the shapes are similar. If they are, then the ratio of volumes is the cube of the ratio of the linear dimensions.
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
Their perimeters are in the same ratio.
Poisson's Ratio of stainless steel
Poisson ratio of most linear elastic material can be anywhere between 0 and 0.5.
What is the poission's ratio in machenical structure ?
0.3-0.2
For elastic, isotropic and homogeneous materials, zero Poisson's ratio means that the material doesn't present lateral deformation on bending, compressing or extending.
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.
0.25 to 0.3 depends on the steel
0,32-0,36
It is pretty low, close to zero.
0.17
It is 0.25
There are test standards to determine poisson ratio. For aluminum, it is 0.33
