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.
What is capacitance ratio?
Capacitance ratio is a measure used to compare the capacitance of two different capacitors or capacitor systems. It is typically expressed as the ratio of the capacitance of one capacitor to that of another, indicating how much more or less capacitance one has relative to the other. This ratio is important in applications where matching capacitance values is critical for circuit performance and stability. A capacitance ratio greater than one indicates that the first capacitor has higher capacitance, while a ratio less than one indicates the opposite.
What ratio provides a measure of a structure's safety?
The safety of a structure is often assessed using the load factor or safety factor ratio, which compares the maximum load the structure can support to the actual load it is expected to bear. A safety factor greater than 1 indicates that the structure can safely support its intended load, while a ratio of 1 or less suggests potential failure. This ratio is crucial in engineering to ensure structures can withstand unforeseen stresses or conditions.
What is critical speed ratio of shaft?
The critical speed ratio of a shaft is a dimensionless value that indicates the relationship between the operating speed of the shaft and its critical speed, which is the speed at which the shaft experiences resonance and can vibrate uncontrollably. It is defined as the ratio of the shaft's operating speed to its critical speed. A critical speed ratio of less than one means the shaft is operating below its critical speed, while a ratio greater than one indicates it is operating above critical speed, which can lead to increased vibrations and potential failure. Proper design and analysis are essential to ensure that the operating speed remains safely below the critical speed.
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.
Can poisson's ratio be greater than 1?
yes * * * * * No, it cannot be greater than 0.5 See link for more details.
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.
