Strain Gauge 3 - Bridge Circuits.MP4

[@jijigem]

I am not from a one of the circuit branches, however it is so nice that you explain from the basics. It makes it easier for a chemical engineer like myself to apply electrical basics in my work.

[@harrynking777]

First class explanation. Not many university lecturers do such a good job.

[@mosialive]

Number 1 Top Rated Lecturer! I'm getting nice marks because of his videos!

[@JayLikesLasers]

I'm glad guys like you give students like me a chance to catch up without having to deviate from youtube, thanks

[@magafonosuper]

Thank you very much for your help. You are such a great professor. This tutorial is SO CLEAR !

[@rionor000]

OMG.... I wish you were my professor. You really made it so clear sir THANK YOU SO MUCH

[@kjNlover410]

I'm in Chemical Engineering so electricity was never my forte, but this helped so much. Thank you!

[@arifozayozbay921]

Thanks for the video, it really helps to understand the circuit.

[@purdueMET]

Glad it helped :-)

[@GoldFoilDecendent]

Great Stuff. EE here attempting to do a science fair experiment with my 8th grade daughter. We're having fun

[@theodoreegling1035]

Great video man. Your explanations are so clear

[@samir12ify]

Great Video, your approach is clear .Thank you

[@afaithforcancer]

Nice basic understandable and clear with application explanation.

[@shanemcdaniel6267]

Awesome thank you. I know this was posted a long time ago. but awesome and still relevant!

[@mohammadkatebi7741]

You are so amazing! Keep up the great job. You made it crystal clear for me! thank you so much.

[@jean50347]

thanks so much, I am really glad to have found this video, I really needed to catch up in understanding this experiment and how it works.

[@saurabhshinde3540]

Great sir. was looking for this kind of explanation

[@vincentvonburen6145]

This was awesome teaching! Thanks very much!

[@severinmundl2710]

Tanks alot! Great way of exlaining things!!!! Best regards from Germany

[@purdueMET]

Wonderful. I hadn't really thought about it, but I'd be willing to do guest lectures or tutoring if anyone ever asked. No university has ever asked, though.

[@lavendertoxic7705]

Thank you so so so much for your video. It helped me understand a lot... Thank you

[@tseckwr3783]

thanks for the presentation.

[@aaronliu9141]

Thank you so much you just explained everything so clearly saved my mid-term LOL.

[@MatMo.]

Incredible, 2-3 minutes in and i was smiling

[@purdueMET]

You're most welcome. I'm glad the videos help.

[@friccarlo]

u r an amazing teacher

[@oriolrd3699]

Thank you very much! Really nice lecture

[@soumenmandal4760]

Thank you sir its really interesting

[@wicked1rish]

wouldnt the resistance go down if the wire wasnt bundled up when pulled to a longer extension?

[@saurabh9978]

helped me a lot, thank you very much

[@SgtScourge]

How do you connect four or two different strain gauges together into a wheatstone configuration like for building a bathroom scale?

[@arlil1]

Clear and concise! This helped me alot!

[@ahmedsoliman1012]

Very helpful!

[@katislam2440]

A very useful tutorial, Thanks a lot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@TheBacoTrein]

Why not use a current source and measure the change in voltage over the resistor?

[@purdueMET]

@arlil1 Thanks very much. If you like the videos, please spread the word. - RMF

[@shivambhatnagar9473]

purdueMET im watching this in 2017...and its helping me a lot...thanks a lot..

[@MataEspanolos]

Thanks for your videos, really helpfull

[@harrywhite7287]

Excellent. Thank you.

[@aimaniskandar6939]

Thank you!! You're my hero!!

[@suryansh4722]

Helpful 🙏

[@purdueMET]

Glad it helped 😊

[@purdueMET]

I ran the numbers again and got (120.06*120-120*120)/(240*240)*12V = .0015V = 1.5 mV I think this is right. Thanks for keeping me honest :-) RMF

[@FrankLopezx]

9:38 i was waiting for this part to come up so good, tho you did skip over some very important highlights you brought up such as amplifiers to boost the 1.5mV ? can you elaborate on that aspect of which amplifier are you refereeing name/model number? also it did not pick up clear on what you meant to say when you placed the strain gauge over the wheatstone bridge covering only R1 "what does this mean for the rest of R2 R3 and R4 ? are they still being used at this point?

[@joelawton123]

Frank Lopez they are still being used. In a q bridge circuit they would be fixed resistors with the same resistance as the strain gauge (when un-strained). This makes your single strain gauge the only variable. A change in resistance due to strain unbalances the bridge and produces an output voltage. You can then use the gauge factor and excitation voltage to calculate strain. As long as you know the test materials youngs modulus you can use the strain to calculate stress

[@phyozinwin]

It's really helpful for me too.. Thank you so much

[@rionor000]

I really don't know how they keep the bad profs at my school :( ... I am not saying this as a complement but I really love the way you are teaching. I might propose some of Electrical Engineering topics and I want you to explain them. Is that OK sir?

[@borisrunakov1662]

Thank you! Great video

[@arlil1]

@purdueMET Will do! P.S your book 'Engineering the Guitar', great too! You should definitely do a youtube video on some of the concepts, excellent job ;)

[@barbiegyi]

Thanks a lot!!!!

[@FrankLopezx]

im building a humanoid robot and im using this as finger tips for end efflector. your formulas should help me on my calculations and predication algorithm for its movement when i do my C++ Classes or function calls

[@philjackson8205]

Thank you!

[@matselanemaphasa8835]

Thnq so much

[@varuninnz]

Thank you

[@govind6198]

its 15 mV sir not 1.5

[@bradfordf.8213]

Please come teach at georgia tech. please.
