Pressure Vessel with Torque - Part 1 - Finding Stresses.MP4

This is part 1 of a two part series. This part shows how to find the stresses on a thin wall pressure vessel that is also subjected to an external torque. Note: At 6:38, I mistakenly write 0.200m for the radius. It should be 0.100m. The resulting number, 41.002 MPa, is correct.

I love this teacher. One minor correction, while calculating the shear stress professor used 0.2 for radius. The final answer is of course correct with the correct radius 0.1

whoever gave this a thumbs down does not see how much talent this man has.

I like the way you teach. My professor talks really fast and never really does problems to their extent. He assumes you know everything. he secretly hates everyone.

@rejzwick Thanks for the encouragement. I'm glad the video helped. I'm planning more.

[@hfell361]

Really helpful thanks. You seem to make difficult concepts easy to grasp. My Uni of Liverpool lectures have a lot to learn

[@adityamorey9251]

how i wish u taught in our college .. amazing .. well done sir .. :)

[@cc2128]

I love you so much!! You saved my degree!

@buddader88 Thanks for catching this. You are right - I should have written 0.100m for the radius. The resulting number is correct, though. When I get some time, I need to re-shoot this video.

Thank you sir God bless you

[@JAVEDKHAN-re2qv]

Very helpful... Will you please guide, how to calculate torque and bending moment for a vertical pressure vessel ?

[@purdueMET]

@hottscorpioo Wow. Thanks for the good news. We professor types dig positive feedback.

[@kabbirhossain7816]

Sir, may i ask why R should be .1, instead of .2?

[@mikeslimjimlim]

solid mechanics is a lot easier with u teaching it

[@baudeagle1]

@lksjadfpjudkloo32 Thanks for the clarification. I am use to dealing the area moment of inertia. Some large horizontal pressure vessels will be supported at both ends causing this type of moment. I am not familiar of any cases where there would be a realistic rotational torsion around the longitudinal axis.

[@luizdemagalhaes748]

could you please do an example with a crack at a certain angle please. thank you

[@shylildude]

is J the area moment of inertia? at 7:27 don't you mean y-z direction for the shear/twist?

[@harisankar8018]

Hi sir. Can you make a video on pressure vessels subjected to axial force

[@EngrTurk]

There are 2 wall thickness one from each side! so, 200mm - 2mm - 2mm = -196 m

[@trialdiy]

whether the theory is also applicable to Rotary Dryer ?

[@baudeagle1]

I was looking at your torque value. You used a value of 32 in this problem, shouldn't this be 64? The inerta for a circle is 1/4 Pi r^4. So for a diameter this would be 1/4 pi (D/2)^4.

[@OoojayAnnooO]

I just want to know how you get the small d? the given is big D and the thickness or t

[@pananaweKing]

Tr/J,,,, r=0.1 sir
