Here also be didn't explained deeply.
But he is good Prof.
What is maximum value of Poisson ratio for linear elastc material??
Answer: maximum value is 0.5 example: Pure elastic rubber, incompressible fluid.
minimum value is 0. example: cork,glass.
For polymer film the range of Poisson ratio is -1 to 0.5( All genetic materials behaves negative Poissons ratio( example: any material with life)
For metals 0.25 to 0.33
If Poisson ratio increase ductility increases.
Generally,
If Poisson ratio is in the range of 0 to 0.25 is called brittle Material.
If Poisson ratio is greater than 0.25 to 0.5 is called as ductile material.
If Poisson ratio is 0.5 (I.e., Change in volume is zero) it is called as non dilatant material .
If Poisson ratio is exactly 0.25 (For isotropic material)
Poisson ration for rigid body cannot be determined.
Why maximum Poissons ratio is limited?i.e., 0.5
For GATE Level deep explanation is required.
excellent explanation s sir. pen was too good very soft looking at it 😄😄
dolly katty hi
thanks for the nice explanation.
Sir ji gjb
Chaa...... Gae guru
Very nice and excellent vedio sir ji

Sir please explain what is stresses due to tightening nut
Nice sir
Thank you dear Engineer .
Nicely explained sir.
thankyou prof. you've been a great help
thankyou sir its really understanding langauge that increase the level ...
Excellent
good explanation
very excellent sir
Super...b sir.....sir what is the unit of Poisson ratio.
your channel is super and its very help full....sir your lecture is so excellent

Sir, limiting value of Poisson's ratio is (-1 to 5) not a (1to 5)...
good
Please define lateral strain
Sir show the important questions in all chapter
example of (-1) po... ratio material
sir i think clarity shuld be increased
sir explain about the 1/m.
sir plz upload the jont truss problubms
Doesn't the formula contain negative sign?
tq sir
You are always welcome!

You should reduced writing time or forward it.....
Healp full sir
Sir but I read it that Poisson's ratio has 0.15 to 0.45
Bhai civil engineering ki
SOM ke lecture dalo
Sorry (-1 to 0.5). Not a (0.1 to 0.5)
SAM Patel (-1 to 0.5) is actual range then other is tho for engineering purpose
SAM Patel sahi kha
Correct
I swear to God we have the exact handwriting 😂
sir please increase the the speed and plese video not show the righting section
Arey Bhai definitions books mein mil jati he mujhe bhi English padni ata he😂socha ta Hindi smjhaoge
bhai vAnchvA nu hoy to amen vanchi jaie
Not understand lesson 😢😢😢
No clarity
if i kiss you will you stop being a frog?
Nice sir ji
