STRAIN: Mohr's Circle & Transformations | Gauges & Rosettes | Principal Plane Stresses from Strains

[@faustasnarunas5454]

Amazing work! Im studying aeronautical engineering, this is my second year (almost finished) have exams on material structures... it is a new subject for us and university. In two weeks i have exam and this is one of the subjects! Thank you very much! This helped me a lot! Fingers crossed i can use your knowledge for my exam

[@TheBomPE]

Best of luck on your exam! Thanks for watching!

I'm glad you liked the video! Thanks for watching!

[@SubhashChandra-ym3tj]

wonderful explanation. Made things clear which are otherwise seems tough

that's how a real professor can teach

[@lasanvagharelu8023]

Sir where we should put strain gauge if the circular shaft is is pure shear ?

[@eriknelson2559]

Would love the Mechanical Engineering Department to take a good look at the Einstein equations of General Relativity, strong suspicion that the tensors thereof can be interpreted as Compliance & Stiffness tensors of an elastic (3+1 dimensional) "fabric" or "membrane" of space-time

[@TheBomPE]

that would be kind of interesting

[@baviquepuspaceno9812]

How can I calculate if the gauges are at 45 deg to each other but offset by 15 deg to the plane axis?

[@TheBomPE]

You can either use the general method I demonstrate here involving a system of equations, or you can use the rectangular rosette equations (simpler) then transform your results using the strain transformation equations I developed here.

@@TheBomPE Hi thank you for responding. This is what I am given for my report: ibb.co/0MSgsXz These are the questions I am trying to solve. Using these strains and the gauge arrangement, construct Mohr’s strain circle From your strain circle, determine (a)The principal strains (b)The direction of the maximum principal strain relative to gauge 1, and check with the gauge alignment on the specimen. (c)E: using the load selected and the bar cross-section, combined with the maximum principal strain. (d)Determine the Poisson’s ratio  from the ratio of the principal strains. (7)Use principal strain equations to check your results obtained from the Mohr’s circle. (Note: make sure you draw the Mohr’s circle to find the results). I am just confused with the offset angle. I imagine if the gauges were oriented normal to the axis, this would become easier to calculate?

[@baviquevirechecantepuspace2615]

So technically I should follow from the 20 min mark to answer my questions?

Sir, much thanks for this work. You're really helping. Do you mind sharing your email address. I'd like to consult further

[@TheBomPE]

I'm glad you are enjoying the videos. I teach at Louisiana Tech University, you can find my contact info on the website there. I do have to filter requests pretty significantly, so please don't be offended if I can't help. Thanks for watching!
