I was so happy when I saw that you do videos on this topic, thank you so much you're helped me very much in my college years and just know that your work is appreciated by people all over the world.
Whenever I don't understand something in my physics book, I just search for one of your videos. You always seem to have videos for any topic I am unsure of, and that's awesome! Thanks a lot.
I appreciate you explaining this out. The way it was taught to me in a Materials class was essentially, "Young's Modulus is a thing, don't worry about where it comes from." This really helps a lot.
Professor Biezen....thank you. Thank you for your natural dedication to teaching, teaching all of us that want to learn i.e. have a clear understanding of what we are doing.
What I could not learned in class, I learned from this video, thank you so much for effort in uploading this video I wish u to upload such kind of video in the future.
in stress the force is not that we apply, it is the restoring force . that means "The restoring or recovering force per unit area set up inside the body is called stress "
There are different definitions for the word "stress". One is indeed the restoring force of the internal molecules pushing back against the force causing the strain. From a practical perspective it can also be defined as the applied force divided by the area over which it acts. Thanks for the input.
Sir, You have given an Excellent explanation!!! I would like to learn more about this aspect of materials, and eventually come to be able to do some basic calculations, where I can find applications for this knowledge, when I desire to build a variety of projects. Thank you, very much!! :D
do you do book or a interacting videos just found your video on you tube and they look great I'm just starting a engineering course and need all the help I can get,
If shearing of a material means plane to plane slipping within an object..........then why do some people use the word shearing during bending... Does bending leads to shearing???? Shearing takes place in one plane...But bending creates sagging and hogging......and sagging and hogging are not in one plane........ Please help me sir, i am confused????
Shearing is the localized lateral loads in the fiber of a material Bending is due to the long distance effects of lateral loads on a material. Think of a bolt or a pin that is loaded in shear, where the two lateral forces applied to the member, are immediately adjacent to one another. Whereas bending occurs where there is a significant length of the structural member between the load and the support, like a beam, such that an internal torque reaction called a bending moment is developed to resist it. Shear loading causes shear stress, while bending moments cause normal stress.
I really appreciate this explanation but some term seems to be wrong. The member you considered should be fixed which is not shown. Either we need to fix it or we should show force at bottom then only stress will generate. The member you consider is not the "beam" but it is the "column". These two words shows the way in which the member is loaded. I think it is better to use the word '"member". Further in the definition of stress , you said it is the "cross sectional area" which is need not to be true always. As in case of shear stress we consider "sheared area" which is not "cross sectional area" In the definition of strain you said it is "deformation/original "shape". The shape of member remains the same. Lets say the shape as rectangle , before loading then generally it will be rectangle only even after loading. It means it is not the "shape" that changes. The change will be in "size". So the definition should be "deformation/original size (not shape). I know this is an introductory video , but we expect more precise content from you.
IbanezV70CE It depends on the context. Pressure is the general definition of F/A. When pressure is applied to an object like a stick, it will stress the material.
sir u are explaining wrong.. stress is measure of restoring force...only in equilibrium... we can say restoring force is applied force...this is not basics..what u claim...so better u DoNt misguide

Wow... In 7 minutes you managed to perfectly explain what was poorly explained to me in class today in 1h15min. Amazing. Thank you.
Thank you so much for this series. I'm trying to understand a Biomechanics paper and these videos saved me so much time and headaches.
you are my hero. I wish i could see you in my life time.
thankyou so much. It's thanks to people like you that knowledge can be shared worldwide.
Start of another series for me in my tutorial marathon. Those kinematics and energy stuffs are superb! Great to be watching your awesome videos!
If you keep that up you will learn a lot!
Yes, you make so much damn sense! I thank you for helping me pass college physics. What an awesome service your videos are. Well done!
***** Glad they are helping
EVERYTHING YOU DEMONSTRATED IS VERY VERY CLEAR AND I APPRECIATE IT. WELL DONE
Thank you for existing!! I am in engineering solid mechanics, wish me luck!!
+A. Kessler Good luck and keep working hard. It is worth it in the end.
I'd missed my first lecture for my physics class, so I was confused all second lecture; this helps a lot!
Your a great teacher please continue your videos you help so many people with bad teachers or even have no access to a teacher :)
That's why we make these videos. Thanks!
Thank you very much for your videos, sir! I'm now getting some hope of passing my A-levels!
lol, me trying to tutor our 100 level students while I've never learnt this stuff, so this helped a lot, thank you!
You are AMAZING. I love you, sir. If I do good in my exam, it'll be because of you.
+Mehra Ahsan ........ur comment indicates ur kindness..................
Kindness must be shown where kindness is due. :)
hmmmmmmmmmmmm..i agree
Great video for revision.
Really helped me visualize and understand.
thank you so much

There are over 5,000 videos on this channel. Enjoy!
Okay, I'll enjoy. Btw, once again thank u so much.
Well explained. Good job sir.
Wonderful! Congrats on your didactics!
I really appreciate this explanation. Thank you for this video.
Sir, I would be very thankful if you upload a tutorial about finding area of inclined surfaces(inclined to some angle) from flat surface.
Thank you very much for posting these videos. They are incredibly helpful.
Naomi,
Thanks for the positive feedback.
love ur teaching style sir
Is there any bigger difference between pressure besides the application? Or it's just the same thing said in different forms?
THANK YOU PHYSICS PROFESSOR YOU ARE AWESOME!!! :D
Thank u for posting this video .
It has really cleared my doubt .
in stress the force is not that we apply, it is the restoring force . that means "The restoring or recovering force per unit area set up inside the body is called stress "

Great explanation!
Bart,
Thanks for the feedback.
Cheer~~~a state of mental or emotional strain or tension resulting from adverse or very demanding circumstances.😢
A great application of "strain" 🙂
do you do book or a interacting videos just found your video on you tube and they look great I'm just starting a engineering course and need all the help I can get,
MATARIAL ANNOYED ME SO MUCH
Make something about
poisson's ratio
Thank you so much....
Thank you so much
thank you very very very very much

nice sir!.
And so my university degree begins....
Engineering.
Nadezhda Dimitrova is this university level? I'm learning this I'm a level?
i am absolutely sure he is professor proton
thanks a lot
wherever you are,i am going to see you personally and thank you someday.I promise you that sir.
Great ! thank you
Thank you
thankyou god bless

is this what explains why things "break"?
+Wesley Black Basically yes.
Pressure= F/A
Stress=F/A
Is there a difference?
IbanezV70CE
It depends on the context. Pressure is the general definition of F/A.
When pressure is applied to an object like a stick, it will stress the material.
I see. Thanks buddy.
