Moment Area Method Example 4 (Part 1/2) - Structural Analysis

In this video, I demonstrate how to apply the moment area theorems to calculate deflections in a beam. This is a pin and roller supported beam with an overhang. This problem is a little more challenging than my previous examples (1-3), since there is no fixed support or symmetry to take advantage of.

Heros don't wear capes they draw FBD's and SOLVE. YOURE THE BEST !!!

[@structurefree]

That's right! And, we shop at Costco.

[@kelekelechristian2814]

3 years later this video is still helpful, super heroooooooo!!!!!!

[@tmcdgreen]

I owe you millions of virtual hugs for this video. Totally saved my grade....

[@tanvirmohammed4590]

You helped me bring my mark up from a 60 to an 80 in my class... I can't thank you enough man! One of the most reliable mechanics channels out there!

[@structurefree]

Congratulations on going from Done to Ballin'! I really appreciate the kind words and sharing your success with me, but I suspect it was your effort more than the videos!

[@dyjIT]

You are like an angel descending from the realm of structural engineering to save my rear end from the upcoming exams here. You're amazing.

[@structurefree]

call me gabe.

[@gnsnbikes]

These 4 examples just saved me from dropping the course! Thank you! Thank you! I just needed a clear explanation! Wish you could teach my whole course.

A-MEN SISTA!!!!!! Structure Free For Prez!!!!

[@idontlikesand1346]

Just had this exact question on the final yesterday and on my way out of the test I howled "STRUCTUUUREEE FREEEEE!!!!"

[@dr.aliabdulhameed]

Frankly, you are perfect and you have all the rights to be always excited.

[@dunknown94]

I have an exam in 2 month your videos are gonna help for sure

[@Chimeratech8]

Thanks man! I thought I understood statics, and then Moment Area method happened. Sigh... But I think I've got it now thanks to these vids.

[@hugosaito]

Dude...you just saved my brazilian ass with this video nice job mah

[@structurefree]

[@Chandu_devavarapu]

At 1:25 how did you got the value of Ay i can't understand.pls clarify that to me

[@SaltyScav]

Is it possible you can do a moment area example for a statically indeterminate beam ? Maybe fixed at both ends with a distributed load on half the beam ? thanks

[@structurefree]

Johnny Collins i probably won't get to it any time in the near future, but if you know how to find reactions (using whatever method) and draw the shear and moment diagrams, then the process is the same.

[@SaltyScav]

structurefree Okay thanks a lot

[@Kamikorosu0416]

+structurefree hi, what is the best way to calculate reactions for indeterminate beams? Do you have anynin your vids? Will appreciate the reply

[@melrodavesantelices4012]

Is the tangent function to solve d and phi ommited?

[@sakunakeang8293]

I wonder if there is any way to calculate a slope at a point on elastic curve by using Moment area theorem for a beam such over hang beam which can not be easily find the point where zero slope locate. thank for any reply :)

[@structurefree]

+Sakuna Keang yes, i believe you can.

[@avielexpatingermany2142]

is minor but at 1:26 the 2nd sum of moments you do is about B not A :D

[@structurefree]

thanks for catching that. I'll add an annotation to the video.

[@bikramoli7096]

How can we find the location and magnitude of maximum deflection in a simply supported beam having unsymmetrical loading?(in Moment area method).

[@structurefree]

Bikram Oli max deflection is likely to occur where the slope in the beam is zero for a simply supported beam.

[@FabioAurelio6]

Thanks mate you're amazing, how did you draw tangent A?

[@YesHerself]

why can't we use the tangent from B to C directly??

[@michaelandreas1409]

what if there is a centralized load between point A and point B? please make a video. thanks

[@omarshams7965]

man u r a legend !!!!!

[@erinsomers4303]

You're great thanks so much

[@alanisami]

I have an exam in 3 days , hopefully it will help

[@itaizrihan5701]

i have a similar question can anyone help me solve it?

[@structurefree]

You should try on your own. 😁

[@mohammadalqahtani1624]

why moment at A=0

[@ymxjack]

Pins and rollers only support forces and not a moment

[@jerimejimenez9704]

I think Reaction @ pt. A must be positive.

[@BongelaMnguni]

BAM!!

[@Djayrocker94]

BAM..!!

[@johnjames2176]

Yeeesss!😂😇

[@mohammadhussein7646]

this is so helpful, but OMG man just use an example with numbers instead of a b P

[@pavstaaaa]

Hi, this message is too late now, my final structure application exams in 9 hours. But it would be useful if you used numbers instead of letters I find it more understandable, just a personal preference :) not sure how many people agree
