Beam Bending: Avoiding Failure

Video covers the basics of beam bending, including: stress, strain, Young's Modulus, area moment of inertia, deflection, and yield stress. An example is used to demonstrate the accuracy of the beam bending equations.

I'm confused now.. why did I spend 1 year to study this where I can get 100% knowledge in this 10 mins video? Awesome video and thank you so much!

[@kenman3756]

You are a credit to your profession and your presentation style is both elegant and straightforward.

[@MistressGlowWorm]

Wonderful lecture and well explained! Thank you!

[@eduardoquintanaavila.6290]

Su estilo de explicar es muy sencillo y claro de entender. Me hubiera gustado tener una maestra asi. Explica tan bien que enamora su estilo. Gracias maestra.

[@mindofganza]

The way you teach is brilliant!

[@DukeLaCrosse20]

Lots of good stuff in this video, but here's the most important point -- the Area Moment of Inertia is proportional to the cube of the height of the beam. Consider standard lumber: a 2x8 beam (oriented with height = 8) vs a 4x4 beam (same length). They have the same amount of wood, but the 4x4 beam will deflect 4 times as much as the 2x8. This is why rafters do not have a square cross sectional area and are often 2x10's or even 2x12's.

[@unpopularopinion149]

Same amount of wood matter. One is twice as long but the other is twice as wide.

[@rezhuq]

Absolutely marvellous explanation! Thank you!

[@rsreisang]

Wish I had such tutorials during my engineering course :)

thanks mam .........nice presentation and i understand it very smoothly... I want know about mohar's circle is any presentation available of u r own?

[@tarunraina1454]

well, if I were to take extra classes on structural analysis, I know who I'd consult, the only problem is, I can't contact you as of yet. But, you did well putting things simply, good job!

[@jonathanguzman1694]

Great presentation, thanks

[@gsureshdagal]

nice presentation!! expecting more on mechanics.

[@wilsonokaka9723]

Brilliant! and practical.

[@pradeepkarna]

superb...ccan u say why we draw shear force and bending moment?what happens physically if shear force is zero ? and what happens to the beams physically if the bending moment is maximum?? ans it soon pls

[@banrath2011]

thanks, it's a good lesson for me

[@noorulhaq7815]

Mam you got a Fan added to your list tody. Thku for such a wonderfull explanation

[@karthic4647]

It was useful for me . I need to know how much load can withstand for simply supported Beam . In that what are measurements i have to take in practical time .

[@MrMARCU5]

Excellent video.

[@kysotope]

best explanation ever.

[@khiemluong4591]

How do I differentiate the width/thickness measurement from the height measurement in a beam?

[@veera459]

Excellent............good presentation

[@munawarhussain7878]

love your video i wish you could make more videos on building design

[@ZombieRevenge777]

If you use your cantilever for a piping systeme support , how do you calculate the dynamic charge of the fluid and then add the dynamic weight to the centalever calculation ?

[@jackCrypt666]

Thanks great video and it was really helpful for me..

[@jeffreycardasto4325]

Thankyou for making this simple, i can now understand it. I am a scaffolder and was really curious to understanding the bendingnof the tubes lol😂

[@thenibxa]

well done on the explanation....

[@anoop0354]

i have few doubts abt monet of inertia. Is there any more videos by Mariya?

[@gerardvong]

Luv your style easy to follow how to follow you

This is very helpful when im just get in civil engineering, why youtube recomend this now, now i feels like wasting alot of time reading textbook to understand this thing Anyways thanks for the video its very helpful

[@mmamun28]

thanx helped me to write my report.

[@karimkhan1312]

i am advocate in india-- i have under stood u r lecture very claerly

[@sudhakardhamane]

Very nice presentation

[@abhayanand1668]

very very helpful..very ery simple

[@mohamedelkady845]

Great. Actually more than great.

[@geraldfelthammer]

Great explanation. I do question the quality of the presentation; I would like to believe that a school as illustrious as MIT would have the budget for a decent camera, lighting and sound. Perhaps a studio? Nonetheless you have done a great job.

[@ponkumarilango851]

Very Nice Lecture

[@alain001]

@enriqueramosvillafan well, yeah, she skipped the explanation of the integral... but there are general rules about it which you can find in tables. it actually just gives you a mm^4 factor which says why the beam breaks at different axis (as if u try to bend the beam normally as shown at around 1:30, or if u try it where u rotate it 90° where u will need much more force to break it (it has more area momentum of inertia..)

[@horiaalbu9306]

You should review the "lever" chapter and in special the necessity to have a point of support, without it you do not have a lever.

[@MountainNZ]

I prefer to consider strain in m/m - Yes you can cancel the units but it reminds you what it means. Its a change in length per unit of length

[@RJGonzalez40]

Hi, i would like to work on a project but have a few questions that might be of interest to a few here. If im looking to reduce a tube 75 feet long to one inch I know I will need to reduce it to 75 inches. How will that apply to pounds. For example let say that that pipe can hold 100 pounds , how will I reduce the 100 punds to apply to the for the to apply the reduction for the 75 inch tube?

[@manishkawale4037]

Suppose there is ductile body which is subjected to bending moment . After calculating induced bending stress . How should I check whether it will fail or not.?

[@fishstyx9705]

How do you calculate in diagonals on a deck beam with 3 posts?

[@barisevran2253]

Great! Thanks !

[@defendermodsandtravels]

Minor niggle. The choice of the failure of the Tacoma Narrows isn't very relevant to the content of this lesson. In that case it was vortex shedding loads causing a dynamic response leading to failure by lateral-torsional buckling. All of these are advanced topics. The video was well presented and much clearer than many others.

[@azarudhinharunrajeeth8815]

can u please upload design calculation for g+1building from safe bearing capacity to beam slab columnZ reinforcement detail and design

[@mohamedhussein9603]

simple and awesome :)

[@norancho]

very nice presentation for a layman like myself.

[@mohanedmohamed7866]

Thanks for these informations

[@ladjkaoz]

Thanks maria... I had underatand beams abit beam better ;) Im a mobil DJ and im building a set up to suspend ligting and audio gear. Most gear would be evently distribuited on 3 beams on a Y shape.. My question is what would be a safe load or max load capacity on this structure... The struccture would be suspended front 3 points.. one at each end of the Y Hope you can help me..

[@davidselin9860]

Great video and easy to follow, I am confused though, i tried plugging your values into the formula s but couldnt get hte same results as you. possibly because I couldn't read the value exponents from your board (I am not a mechanical engineer,but i need to understand as i am building a canopy over double doors. The values I have as as follows:- F=0.5 N, L=0.25M, b=0.025M h=8x10^-4M, E=69x10^6Pa, I=1.07^-2 M. I am many orders of magnitude out. I get 3.51^-3 mm and 4.67^-3 Mpa respectively. Where have I gone wrong?

[@padmanaban087]

Thank you very much madam .. very useful

[@kenalichannel]

Thanks!

[@sadiqqurishi]

Useful lectures

[@gadha707]

2:45. Were each of those two classmates (tall and short) grew 1 inch naturally? Or were they pulled along their lengths and thus both experienced elongation of 1 inch? I can only see strain on them if they were pulled. Btw, it is highly likely that the tall dude came back to his original height once the force was removed whereas the shorty exhibited a plastic deformation and gained 1 inch of much needed height permanently!
