In this video I will explain the bending moments caused by a load on a beam.
Next video in this series can be seen at:
• Mechanical Engineering...
I had never seen any teacher of solid mechanics who can so clear and so easy explain semester course in 5 minutes. Thank you so much!!!
Sir, I should be paying my tuition fees to you instead of my university.
This is by far the clearest way I've seen this topic taught- thanks very much
Every other video or textbook just goes on explaining how to calculate BM or SF but none of them explain what exactly is happening inside the beam
I am a masters student and I found this video helpful.
Cheers!!!
that's why I didn't enroll for masters. They just want to take the money.
I wish I would have watched your videos before the quizzes..thank you for great explanation.
maybe before the next quiz?
Your class is more valuable than a lot of university courses!
Thank you. We appreciate the comment.
i have reviwed many many videos in this topic and thid is the best one who clearly ecplain this point.
You are 90% of the reason I'm not failing Electricity and Magnetism and Statics. Thank you, sir.
Very clear explanation. Great stuff!
Wonderful video I can always rely on you to clarify things
thanksssss now I understood it . you saved my life
thanks,
your explanation is very simple and easy to understand
Great explanation sir...i was struggling with this concept for past 1 month...thank you so much
Glad we could help. :)
Very nice explanation!
Thanks a lot sir.
Love you from Bangladesh🇧🇩🇧🇩
Thanks and welcome to the channel!
Your description makes sense.I’ve started to understand shear forces and moments reactions,thanks
Great! It is a tricky concept and at first counter-intuitive.
i cannot praise this video enough....your teaching is so good that even though I sit through my civil engineering lectures totally confused, I am relaxed, because i know Michael Van Biezen's videos will save me...all other lecturers should just quit
This really helped me, click to get that 'ah ha' moment thank you Professor Van Biezen. About a yr ago i said the same thing on another one of your videos and you replied, so you're helping me over a prolonged time now.
Great! Yes this concept is a mind bender as it appears to contradict what we have learned about forces and the moment.
@@MichelvanBiezen I can't thank you enough for putting this content out, I wish I was more fiscal to say thanks that way.
But your help is often the difference between giving up with this study (which often feels overwhelming) and carrying on.
I've tested myself as a visual, kinetic learner and I'm studying at home with 100's of pages of dry text book reading to do, and I say I'll do 10 pages a day, but then hit a brick wall of not getting something or I'll spend an hour on one page alone. So although you put this out 7 yrs ago, take comfort in the fact, you're still helping people today and you'll be helping people probably long after you leave this mortal coil. That's pretty cool.
Edit I'm getting to the point where I'm trying to watch, take notes from your video series before I do the text book reading, just so I can visualise it better. So again thank you so much.
Excellent. You have found a way to be succesful. Keep that up. Glad we are able to be part of your journey. 🙂
Very clear explanation. Thank you so much
best method of teaching
Thank you sir, It was really helpful.
it's clear to understand
great explanation!
Thank you very much. Your video are best video. Great !
best simple explanation by far on youtube!
Thank you. Glad you found our videos. 🙂
I would tankfully say that, your channel on CZcams is priceless
Sir, can you explain how do we prove that the bending moment for beam similar as above (but without the Force in the middle, just 2 forces at the end from the supports) is constant? Really appreciate it!
i think i just got a big concept - the bending moment arrows are reaction forces not the forces placed on the beam from the load
That is correct.
@@MichelvanBiezen Will it be corect to say that, those reaction forces are caused by the load placed on the beam and without the load they wouldn't exist? Just trying to grasp the concept really!
Great explanation sir rather then going to college it's better to watch your videos
crystal clear explanation
Sir,
On a simply supported beam BM is max at centre and zero at support so does that mean we have maxm strain at centre section and zero at support?
Nice explanation sir
Thank you for the best explanation Sir.
You are most welcome. Glad you found our videos. 🙂
How on earth someone can easily explain bending moment so simple like this!!!
Thank you. Glad you liked the video! 🙂
Sir I am an Indian, sir you explain bending moment in this video very essay way . Thanks 🙏 sir
Thank you. Welcome to the channel! 🙂
You r great sir .sir I salute you
Excellent sir
YOU SIR. ARE AMAZING>
thanks a lot sir
Very clear, thanks!
You are welcome. 🙂
I never comment on youtube videos but I just wanna say you are a really good teach
Thank you
Thank you 🌹
Great......
Very clear explanation sir. thank you so much
You are welcome
Sir please keep bestowing students with your knowledge
Thank you sir! Please take more videos
As long as we are able, we'll continue to make more videos.
Beautiful
That was awesome method. 🙏🏻
Glad you liked it! Thank you.
Excellent explanation
Thank you. Glad you found our videos.
this dude is a ledgend
Glad you found our videos! 🙂
Wonderful explanation
Glad you think so! This can be a very tricky concept as it appears counter-intuitive when one first sees this.
Thanks ,Sir
Thank u very much sir
THANK YOU
god bless this professor🙏
Thank you kindly
thank you so mutch !!!
You're welcome!
Sir, thank you.
You are welcome.
thanks
Sir...How can we determine the direction of shear force???why cannot we take it in opposite direction as you mentioned??
I spent one semester just to figuring out what exactly was my lecture talking about those arrows.
I dont get why the arrows are pointing away from eachother on the top...during a sag, arent the forces pushing into eachother on the top and away from eachother (like streching) on the bottom?
These are the reaction forces. They oppose the bending of the beam.
So positive moments are moments that OPPOSE, react against the bending/deformation of the beam?
This video is specifically covering BENDING moments of the beam and that is how they are defined.
Where i can find the cantilever related problem in your video.
We don't have anything specific an the cantilever. :(
I finally get it now and it took 5 minutes
Great! Yes, this is a tricky concept (and counterintuitive)
what a man
why moment 2 is positive it is clockwise should be negative ?
As explained in the video the moments are considered positive by convention as they are caused by the internal forces of the beam.
If this internal moments action oppose to bending of the beam, how beam bend?? Plz explain sir...
Opposing the bending does not mean that the beam doesn't mean the beam doesn't bend at all , but that it will bend less.
Why is there a miniature violin in the corner of the board?
Just to keep things interesting.
