Just discovered this channel. I'm taking Strength of Materials in Germany, and I only speak a little (B1 level) German. I have a tutor but he's only available so much.... anyways, I'm totally watching these videos and filling in the gaps. Looking at all the videos, it's TOTALLY the same stuff we're doing in my class. Of course, the material is the same everywhere you go, but nevertheless, it's awesome! thank you!
Hey Anthony thanks for letting me know, I'm really glad I can help! This stuff is hard enough in English, let a lone a second language. I was pretty sure the material was transferrable so glad to confirm that it is!
Were you fine in your course? Did you learn enough German? Cause I know the higher level course don't have many youtube videos. But of course there is still books
Thank you for your great knowledge! This helps a lot more than the 1hr + lectures that drag on explaining concepts in the most ridulous language(using complex words)
Technically this video is talking about average normal stress. It's just the force divided by the cross sectional area, and we assume a uniform distribution all over. In reality, it's not uniform, it's stronger in the middle. But most analysis at the introductory level of mechanics of materials deals with average normal stress.
It’s usually an abstraction of applied force and reaction force. This video just has an arbitrary rectangular member floating around in space, so if we want to apply a force (P) to it, we need to have an equal and opposite force (P’) to keep it in static equilibrium. IRL, the force we apply would be P, and P’ would usually be provided by a reaction force. But drawing the reaction on the member just is kind of irrelevant to the abstract member we have drawn. The exact type of reaction doesn’t matter really, so long as you have the tension or compression existing within the member. So that’s why we just use P and P’. Hope that makes sense.
@@Engineer4Free I see, thank you for the clear explanation. My exam for this course is in a week, and your videos really helped clear things up, so thank you so much!
"Mechanics Of Materials" by R.C. Hibbeler seems like a very good book. I definitely know that his books on Statics and Dynamics are awesome, and "Mechanics Of Materials" seems to have the exactly same structure as those books.
The Modulus of Elasticity is a number that measures an object or substance's resistance to being deformed elastically. I recommend checking out the wikipedia article for a quick summary:en.wikipedia.org/wiki/Elastic_modulus It also represents the slope of the elastic region on the stress strain diagram for a material, I made a video about that, you can see it here: www.engineer4free.com/4/hookes-law
It is kind of strange how I find these short videos much more helpful that many of the hour-long lectures of my class lol
No bullshit fast delivery, no time wasted. Great lessons thank you so much !
Amazing feedback! Thanks for watching 🙂🙂
This guy is saving my semester thanks so much man!
Glad I can help :)
you graduated yet, sir?

Great work man...
Highly appreciable...
Can u please tell me which software u use to do all this stuff.....
Hey Manas, thanks for the compliment! You can find the full list of my hardware and software at engineer4free.com/tools :)
Manas Sir appreciating Eng4Free, amazing. Two most valuable treasures on youtube.
nice work !, thank you. you just saved my semester
Awesome, make sure you check out engineer4free.com/mechanics-of-materials if you haven't already. Feel free to share it with your class too :)
I wish I had discovered this channel sooner< Anyways Thanks a lot man. You're a real life saver
Better late than never!! Hope you get a lot of use out of it now that you know 😁
Hi I commented on one of your solids videos before. Fantastic videos again for this class. Thank you so much for creating these videos!
Thanks for sticking around Nick! Glad you are liking them :)
Hi, it is a great tutorial sir, but i wonder, what software like whiteboard do you use ?
it is interesting tho
You can find all of the hardware and software that I use here: engineer4free.com/tools =)
Any way I can get those notes? Thanks for the video btw!!!
Hello, I really like your videos. What software do you use for the presentation?
Hey Steve, I’ve got a full list of the hardware and software that I use to make the videos at engineer4free.com/tools you should check it out 🙂
Very helpful video
very helpful videos. Is it possible to share how you make these videos?
Hey yep, you can find all of the hardware and software that I use to make the videos at engineer4free.com/tools 👌👌
Sir plz upload more video for mechanical student...you are great sir.. Thank you so much sir..
Working on it brother!!
Good work man
Thanks Bonthu =)
Very concise. Thanks
Perfect, thanks for the feedback =D
thanks a lot! very helpful
Glad it helped! Do check out the rest of the playlist here: engineer4free.com/mechanics-of-materials =)
Which textbook do you recommend for this course
What if we have an angle instead?
What is the name of the software you are using to draw these examples? Your response is appreciated.

Luv this video
Good work sir...............
100% helpful
Thanks Jamshad! Make sure to check out the entire set at engineer4free.com/mechanics-of-materials if you haven't already :)
GOOD VIDEO!!, GREETINGS FROM MEXICO!!!
Thanks Axel!!! =) =)
do your platform provide any notes ?
Hey sorry but generally no... Just the videos on UA-cam. You can check out the whole playlist though at engineer4free.com/mechanics-of-materials =)
So what is the difference between normal stress and average normal stress Sir ???
Technically this video is talking about average normal stress. It's just the force divided by the cross sectional area, and we assume a uniform distribution all over. In reality, it's not uniform, it's stronger in the middle. But most analysis at the introductory level of mechanics of materials deals with average normal stress.
How about angular cross section
Why is the website not working?
Thanks for letting me know. I broke it for a few days while changing some settings. It's back up again!
1N/mm^2 = 1MPa
Not a bad thing to also memorize :)
why does professors write P and P' like you did in the video? what's the difference between P and P'?
It’s usually an abstraction of applied force and reaction force. This video just has an arbitrary rectangular member floating around in space, so if we want to apply a force (P) to it, we need to have an equal and opposite force (P’) to keep it in static equilibrium. IRL, the force we apply would be P, and P’ would usually be provided by a reaction force. But drawing the reaction on the member just is kind of irrelevant to the abstract member we have drawn. The exact type of reaction doesn’t matter really, so long as you have the tension or compression existing within the member. So that’s why we just use P and P’. Hope that makes sense.
@@Engineer4Free I see, thank you for the clear explanation. My exam for this course is in a week, and your videos really helped clear things up, so thank you so much!

You're welcome!!!
hi, which book do u recommend as a source book?
"Mechanics Of Materials" by R.C. Hibbeler seems like a very good book.
I definitely know that his books on Statics and Dynamics are awesome, and "Mechanics Of Materials" seems to have the exactly same structure as those books.
Why v use Word MODULUS?
Where it came from??
Wt is its meaning????
Sir pls answer if u don't mind
The Modulus of Elasticity is a number that measures an object or substance's resistance to being deformed elastically. I recommend checking out the wikipedia article for a quick summary:en.wikipedia.org/wiki/Elastic_modulus It also represents the slope of the elastic region on the stress strain diagram for a material, I made a video about that, you can see it here: www.engineer4free.com/4/hookes-law
I think, I went to wrong places, by the way Finally here.
Glad you found the videos. Full playlist is here: engineer4free.com/mechanics-of-materials =)
i think the answer becomes 40kpa
0.04 GPa = 40 MPa = 40,000 kPa = 40,000,000 Pa
It's mm ^2, not KN/mm
@@Engineer4Free I got the answer 40 KPa. If you convert 50mm to m you will end up with 40,000 which is 40 KPa
ur right man. 0.04 times a thousand for the K sign times another thousand for mm^2 to m^2. that would be 0.04×1000×1000=40000Pa=40KPa.
