  1. I have a problem that in problem number 1 , you have taken volumetric strain = hoop stress + longitudinal strain but in problem 2 , volumetric strain = 2(hoop strain) + longitudinal strain. Not getting the concept!!

  2. where are the videos of thick cylinders .I am loving ur videos and clarity of thin cylinders but.. no videos of thickcylinder

  3. sir. great work. now o dont have to study longer in those large books. simply explained.
    i have a question . can u please anser.
    question – A thin cylinder with both ends closed is subjected to internall pressure p. the longitudinal stress at the surface has been calculated as sigma , max shear stress will be equal to… ( my answer is 0.5 sigma) is it correct?

  4. can I use the hoop stress to find the change in length and longitudinal stress to find the change in D

  5. Sir thanks for clear understanding… One mistake is happen while calculating volumetric strain. The correct formula of volumetric strain us equal to sum of longitudinal strain and 2 times of circumferential strain.

  6. sir, at 14:00 minute, to find out change dia you took original diameter as 250, why not 260(while it has 5 mm thickness, so 5+250+5)? and later please have a look on formula for volumetric strain.
    thank you sir, your lecture is impressive
