You do such a great job of explaining the problems step by step!!! Thank you sir!!! I was feeling worried about my first few classes but feel much better now!!!
Glad I could help. Stay on top of your coursework and study. you will do fine.
OOOOOHHHH MYYYYYY GOD!!!! THANK YOU SOOOOO MUCH FOR THESE VIDEOS!!! I have been struggling for a while now and could not find a tutor or any detailed videos until I stumbled upon yours. I have been so stressed out trying to figure this stuff out with out any help. You literally just saved my butt from failing my class! Thank you, Thank you, Thank you!!!
This video series truly helps me fully comprehend what it is that is going on in my class, thank you so much Dr. Stewart, your work shall not go unnoticed.
Thanks!
I am going through your lectures again with great care. They are extraordinary.
Glad you like them!
didn't expected this quality learning experience from a non-Indian teacher
DR. Stewart ,thank you so much for explaining and solving each problem in detail. The review of Trigonometry and Geometry is also very helpful.
your videos are very helpful and I thank you for posting them and helping me learn
+GetDookied you're welcome!
Dr. Stewart, you do an awesome job with these explanations sir. Thank you for making these videos available to everyone.
Thank you for explaining this. It took some time but you've helped a suffer of dyscalculia today.
oh god this is great! i was so worried because i couldn't catch up on the lecture but your videos help me A LOT! may god bless you :)
I am now in 7th semester and still i can remember these lectures i saw in my first semester and these helped me alot... ❤..
Thank you Dr. Stewart, these videos are so helpful. Would you happed to have to solution to the last problem (Fundamental 2-3)?
I would like to say Dr. your a savior I started to question whether I can continue in engineering of how lost I was.
been watching your videos and they are greatly helpful thank you and god bless you.
Thanks a million from a student at the Delft University of Technology!
thanks doctor Steward.
I believe that it is F2-5 from the book because if you take a closer look it is the from the video. :)
Was the problem we were supposed to do, Probelm F2-3 from the video, or Problem F2-5 from the comment?
Great Job U R doing Great work .....Sir I have One query that Can we suggest Any one vector from three A Resultant Force Or always the Middle One?
I love your videos. Thank you Sir
Thank you for the explanation ..they are helpful
where is the video which you solved the homework that you gave us
I am having a lot of trouble getting the value of gamma using the law of sine...I keep coming up with decimal places I structure the equation the exact same and still get messed up...(150sin(115))/212.6=.667 then asjn(.667)=a crazy decimal place that isn't close to 39.8. I know I must be looking at the equation wrong but cant figure it out. HELP
well, the answer is not 0.667 but 0.639. asin(.639) is 39.71 deg
may i get solution please
The post is to be pulled out of the ground using two ropes A and B.
Rope A is subjected to force , F1 and is directed at angle θ1
from the horizontal. If the resultant force acting on the
post is to be FR, vertically upward, determine the force T
in rope B and the corresponding angle θ.
Given:
FR = 6 KN
F1 = 3 KN
θ1 = 60 degree
Can you send me the solution of the last problem
at 21:27 can anybody tell me why on upper side of the diagram there is 30 degree angle why explain
your playlist is really helpful thank you
I glad I could help Mr. Castro!
Im in your spring 2015 class and we already saw this sections but I am still stuck with a problem similar to Ex. 2.1. We had some in the homework the only difference is that some forces where in the 3rd quadrant, i would like to see you solve an example with forces in the 3rd quadrant please, because I get confused on how to manage the angles that are 'negative'. Thank you
Since in the examples you only work with forces in the first two quadrants.
Elio Tapia In a problem where the force vector is in the 3rd quadrant, the angles will not be negative. (Angles are described relative to an axis and thus should be positive quantities) The negative sign comes from the direction of the force components. If a force vector can be broken down into components and those components are going in the negative direction (compare to the assumed positive axes) then you will place a negative sign in front of the term. Hope this helps!
how do you know the sense of the components u and v from the beggining of the problem?
You are the best
hi Stewart , just discover your video and its really helpful specially for static beginner like me,,,just wondering about the group exercise at the end of this video, I tried but I get stuck at the parallelogram rules...is that any video show how to break out this exercise?
Thank you for the videos, they are great
+robert margolies you're welcome!
Thanks for explications!
Is there a video solution for the group problem anywhere?
thank you
I like your teaching thank you.
Whats wroung why i cant see the full leacture?
Awesome sir 😍
u so great Sir!!!
Thanks!
HI, DOES ANYONE KNOW THE BOOK'S NAME SIR IS USING?
Thank you Sir.
Can you give us the lecture notes in a pdf file? That will be really helpful.
+Hridoy Debnath Hello Hridoy, The best method to use my videos is to write notes as you follow along. ;-) Often in my videos I say things that are key to understanding the theory but are not found on the screen. By writing your own notes in your own words your understanding and retention of knowledge will increase. Best of Luck. Dr. Stewart
Okay thank you Professor, will do. One more question, which book are you using to write these notes?
I am a mechanical engineer student from City College of New York, NY and we are using, "Vector Mechanics for Engineers 10th Edition" by Beer, Johnston and Mazurek.
+Hridoy Debnath Hibbeler Engineering Mechanics: Statics
i got AB 217 and i got AC 159 am i wrong anyone tell me please
tank you alot
Isn't sin law limited to acute angles??
Natallie May Intila Nope its not, it can be applied to any form of triangle, acute or obtuse angles it still works.
Yup! Got the answer on my lab class. Just got confused. Thanks btw!
How did you get the 2.65°?
Thanks
Hi
Nice job
thank you
+Hosni Taleb you're welcome.
hey, do u have your notes as pdf files?
Yes. Go to the website -> me.utep.edu/cmstewart/me1321.html
İ am watching you from turkey 😅
Fab=772.8 lb , Fac=565 lb
Could you please send the solution of exercise 5.1 fundamental problem?
+Jhasllan Martins more example videos will be coming in the future
+Calvin Stewart thanks anyways but I have finished this Mechanics course, Thanks
hey calvin my name is alphons i just want to say this video is really helpful. Is there an email i can send you problem that i am trying to work on from a book it is applied mechanics for engineering technology eighth edition author is keith m walker.
Hello instructor :D
+Görkem Biner Hello Mr. Biner.
some one answer me please
I wanna marry you dr, thank u very much your explanation is outstanding.
maybe that wud be a punishment for him?? not a reward.
