If you stretch an object, each side changes length by an amount due to strain,e, so the new length is L(1+e)..Each side normal to the stretch direction contracts by an amount equal to poisson ratio x the stretch.
If you calculate the change in volume V you get
dV = Ve(1-2u)
Ay u = 0.5 there is no volume change (incompressible); if it were greater than 0.5 volume would decrease which is unlikely. If it is 0, there is no lateral contraction and volume increases. If less than 0 the object will actually expand laterally rather than contract, and some special materials do this. Poisson ratio can be as low as -1, but most common materials lie between 0 and 0.5
What else can I help you with?
Can poisson's ratio be greater than 1?
yes * * * * * No, it cannot be greater than 0.5 See link for more details.
Why multi staging is required for air compressor?
If the pressure output of the compressor is approx. 10x greater than atmospheric pressure, the compression cannot be completed in one stage without inefficient power losses.

Will steel pipe float?
Steel pipe will not float in water because it is denser than water. The density of steel is significantly greater than that of water, which is why steel sinks. However, if the steel pipe is hollow and filled with air, it may float depending on its overall buoyancy, which is determined by its shape and the ratio of its volume to its weight.
What is the current ratio of Current Reserve Ratio?

Can poisson's ratio be greater than 1?

Where is the greatest ratio of women to men?
In a room in which there was only one woman and no men, the ratio would be infinite. You cannot get any greater than that!
Prove that poissons' ratio is 0.5?
since k=E/3(1-2n): where k=bulk modulus and n=poision's ratio it can be seen that value of poision's ratio can't be smaller than 0.5 in order to keep k be +ve.hence poision's ratio is 0.5
Where would you find a point with a ratio greater than 1?
Any point where x/y is greater than 1 has a ratio larger than one. For example, the point (2, 1) has a ratio of 2:1, or 2. (3, 1) has a ratio of 3, etc.
Is the tangent ratio number is greater than one?
The tangent ratio can take any real value.
How do you calculate compression ratio?
compression ratio = compressed size / uncompressed size the ratio should be between 1 and 0 (multiply with 100 to get the ratio in percent) a ratio greater than 1 means, the compressed size is actually greater than the uncompressed size a ratio just below 1 means bad compression the lower the ratio, the better the compression
Why can't the probability be greater then one?
A probability of 1 means something will definitely happen. There cannot be a greater certainty than that, so probability cannot be greater than 1.
What is 'portrait orientation'?
A vertical to horizontal ratio greater than 1.
What does it mean when the ratio is greater than 1?
When a ratio is greater than 1, it indicates that the quantity in the numerator is larger than the quantity in the denominator. This suggests a favorable or positive condition, depending on the context. For instance, in financial metrics, a ratio greater than 1 might indicate profitability or more assets than liabilities. In other contexts, it can signify a majority or dominance of one element over another.
When is a slope ratio more than 1?
A slope ratio is more than 1 when the vertical change (rise) between two points is greater than the horizontal change (run). This occurs in scenarios where the angle of the line is steep, resulting in a steep incline. For example, if the rise is 5 units and the run is 3 units, the slope ratio is 5/3, which is greater than 1. In general, a slope ratio greater than 1 indicates a steep ascent.
How do you compare a ratio using division?
Divide the first ratio by the second. If the answer is less than 1 then the first ratio is smaller. If the answer is equal to 1 then the two ratios are equal. If the answer is greater than 1 then the first ratio is larger.
Can you simplify the ratio 67 53?
67 and 53 are both prime numbers, meaning they only have factors of themselves and one. Because of this, they have no common factors greater than one and cannot be reduced.
