Minimum and maximum values of possion’s ratio for a metal lies between
Poisson’s ratio is the ratio of the lateral strain to the longitudinal strain when a material is subjected to stress. It is a measure of the material’s ability to deform in one direction when stretched or compressed in another. The value typically ranges from 0 to 0.5 for most materials.
Chapter 8 of Class 11 Physics focuses on the mechanical properties of solids. It explains concepts like stress strain Hooke’s law elastic and plastic deformation Young’s modulus bulk modulus and shear modulus. The chapter also covers the effects of force on solids their deformation under stress and how materials respond to stretching compressing and bending forces.
Most metals have a Poisson’s ratio in the range of 0 to 0.5. A value of 0 indicates no lateral contraction when stretched, and 0.5 represents a material that maintains constant volume under deformation. This is theoretically true for perfectly incompressible materials.
