What is the poission's ratio in machenical structure ?
The ratio of lateral strain to the longitudinal strain is called as poissions ratio
The poission ratio of orthophthalic polyester resin it's 0.37.
lateral strain/ longitudinal stress= poission's ratio

rubber is the highest; it is nearly incompressible and results in a Poisson ratio approaching 0.5, the highest possible value.
No. A higher P E ratio can result in much better results than a lower P E ratio, but it is a lot riskier. Meaning a higher risk of loss for the higher P E ratio.
A glass ball will bounce higher than a rubber one.
There is a component of the total drag of an aircraft called induced drag that depends inversely on the aspect ratio. The length of the wingspan is a key element in calculating aspect ratio. Aspect ratio is defined as the square of the wingspan divided by the wing area. The higher the aspect ratio of the wing, the less induced drag it creates and a slightly higher lift is generated than a shorter aspect ratio wing. In other words, long narrow wings fly easier than short stubby wings, and they stay aloft longer, all other elements being equal. That's one reason commercial jetliners (and the albatross) have such long wings compared to jet fighters (and hawks). That's also how the wingspan of the theoretical rubber engine airplane affects the airborne time of the plane.
