I love this. Thank you Dr Stewart for thoroughly explaining everything. Currently busy with my Chem Eng degree and you have clarified all the questions I had on this topic in the first 7 minutes of this video!
Finally i get to understand these types of questions, doc you are seriously awesome. Please do not stop making videos like these.
JR. Mechatronics student here
+Omar el emary I'll try to keep it up.
I am indebted to you sir, basically, varsity is not the place where I am taught, it has always been youtube. and you are the #TH-cam for statics, genius man, simply genius ..........!!!!...
Your videos have been tremendously helpful in my current statics class as well- I don't attend UTEP so I never really commented on the videos, but at my university we're also using the same text book and you seamlessly break the information down. I don't really feel the need to attend class anymore to be honest (but I still do of course lol) and I'm doing great on quizzes and hw because of your videos. Nonetheless not sure if this was only for your students at UTEP, but it's been a major help for me and I know it's been a help as well for other students studying statics and especially those using this particular textbook. So thank you sir for your time and effort
You are welcome! Make sure to attend class it is still important.
posting and making these videos are very helpful doctor i want to say thank you for helping out everybody that sees your video understand a subject that is already difficult as it is and to break it down to parts much easier to comprehend once again thank you
You're welcome Chrys!
Thank you so much Dr. Stewart! This helps so much.
Glad to help!
Thank you Dr. Stewart... You've helped a lot.. All these concepts are usually difficult to understand in a large lecture hall.. You've taught everything thoroughly in a step-wise manner.. Thank you.. God bless you
you are a legend at my college.
Thanks! I think?
Thank so much .these lectures are so helpful to me .I find less stress with stactics and i solve all problems in my textbook without difficulties.My lecturer for stactic really gives hard times in class we barely grab understanding during lectures and he very fast.Now with your videos my problem is solved.thank you so much once more
Raissa Smiley Glad I could help you.
this is awesome. Thank you very much Dr. Stewart. This class should only be taught by professors like you.
+Abdullah hmd Thanks! Good luck in your studies Abdullah.
Man. Dr. Stewart is so elaborate.
this has been incredibly helpful in my current statics class
Glad that I could help. Good luck with your studies!
Great lecture Dr Calvin
I learned and enjoyed alot
great video! helped me a lot for my tam 210 exam. wish there were more example videos since they are all really helpful!
+George Popovic examples videos take alot of time to create. sometime in the future.
I wish you were my professor. Thank you!!!
+Tetiana Derkach I'm flattered Thanks!
excellent quality, best video ive found. thank you!
+misterlink2 you're welcome!
awesome work sir ..i salute u.u deserve 1 million subscribers ..sad to see that students are not subscribing to your channel...but a day will come when you will get 100k and so on...Best Wishes to u Sir.........
appreciate you professor!
Thanks for your effort. Appreciate your help.
Wonderful explanation !
Thanks!
For the first problem, I don't understand why do we have to assume that the position vector rx is to be 0.6i, cant we calculate it?
Thank you! I was very confused for this section prior to watching this video. This was very helpful! Do you plan on recording explanations for more examples from the book in the near future?
thanks a lot dr for your help
thankyou sir! it helped me alot
thanks doc, most explanatory video ever !
+Hashim Bello Glad I could help!
+Calvin Stewart
Dr.Stewart thank you for your amazing videos. I'm wondering why we should always choose the r vector to connect an arbitrary point ON OUR DESIRED AXIS to the line of action of the F?
Why not let it be the moment about any point in the space and then let the dot product with unit vector do the job and project that moment on the axis?
Thanks
Great! Thanks for sharing your knowledge!
+Felipe Oliveros you're welcome!
Your explanation is magnificent as always but correct me if I'm wrong . "The dot product equation to find the moment at a certain axis". so It's not just the x,y,z axis ? I mean why did you use this equation in the first place shouldn't we use it if we want the moment at the x.y,z axis ONLY ? "assuming that Mab is the MR of the Mx,My and Mz "
Hello, in the second problem why did you use Rod instead of Rac, I thought we can calculate the lenght of Rac with rooth of (0.2^2 + 0.3^2 )
salute you sir........well explained
very extremely amazing explanation....please solve many problem from meriam book unit 1$2
I use the Hibbeler Statics book but Statics is Statics. Once, you've mastered the concepts you can solve any problem. :-)
thankYou Dr
truly appreciated
BLESS YOU!
sorry may i ask that how can i know when the F need to multiple with u first then substitude into the matrik form or just can directly substitude the F inside the equation?
thank u dear sir ..now i clear about the topic and basics
in the second problem you chose the position vector r-od that connects the axis from point A to line of action. Would the answer vary if you chose any other points, for instance r-ac as the position vector?
+Minh Pham you can use any Position Vector that connects the Line of Action of the Force to the Axis of the Pipe. OD, OC, AD, or AC.
Calvin Stewart In the second problem I tried using rAD and I got a slightly different answer
You are AWESOME :D That helped a lot for tomorrows exam.
I hope you did well.
Calvin Stewart Yeah I nailed it, thanks a lot.
hello sir can you explain that how do you take value of r like the on in second problem I can't understand please help?
Do some probloms on truss analysis
A bunch of new videos have been uploaded. See the Method of Joints, Zero-Force Members, and the Method Of Sections examples.
would you mind putting examples for more chapters. And I really like your work
I have a question, for example 4.8 you used position vector rx as the line connecting AB and the line of action of the force. Could you not also use the position vector you labeled rc?
sorry haha, I commented this like midway through the video, you answered it later on. Thanks for these videos they are REALLY helpful for my midterms! :)
Hi, sorry teacher I've a question at point A(0 0 0) B(0.4 0.2 0) and than vectors of these points is equal to 6.4i+0.2j it's true?...
You have a typo you put 6.4i+0.2j which is incorrect. The answer is r_ab = r_b - r_a = 0.4i + 0.2j.
Bless you sir!
Danko man 🔥🔥🔥🔥🔥
Hi teacher I put a question in other comment about this video; please reply it.
see my answer.
Professor Stewart, thank for another straight forward example of Moments about a Specified Axis and it's importance in Statics. These problems are challenging in Statics.
what book are you using sir???
Engineering Mechanics: Statics by Hibbeler
What is the value of Mars = ? hehe .. put some humor here .. anyways this is good tut. nice one Sire. :D
Woowww
Weeeee.... :-)
"Position vector r is any position vector that connects the axis of interest with the line of action of the force"
Brilliant, thanks so much.
