Materials show varying behaviors based on their Poisson's ratio. High Poisson's ratio materials (near 0.5) contract significantly sideways when stretched and expand when compressed, seen in substances like rubber. Low Poisson's ratio materials (near 0) undergo minimal width change during axial deformation, typical of metals and common engineering materials.

Mattrab Community - SXC • asked a question

Log_2aa=x then, a=(2a)^x ......(1)

Log_3a2a=y then,2a=(3a)^y ......(2)

Log_4a 3a=z then, 3a=(4a)^z ......(3)

So,

a=(2a)^x [from (1)]

Or, a=(3a)^xy [from(2)]

Or, a=(4a)^xyz [from(3)]

Multiplying both sides by 4a,

4a.a=4a.(4a)^xyz

Or,(2a)² =(4a)^{xyz + 1}

Or,(3a)^2y =(4a)^xyz+1

Or,(4a)^2yz =(4a)^xyz+1

Or, 2yz = xyz+1 .proved.
