Moment Distribution Method Example 1 (1/2) - Structural Analysis

[@PK-zo8lx]

I can't believe how easier it is for the newer generations of engineering students to learn these concepts. When I was in University in the late 80s we had very limited (dial-up !!) Internet and certainly no KZbin. We had to haul our a%% in the campus library, dig through pages and pages of other books (in addition to our textbooks) , find material that was better explained than our prof would explain, find coins to insert in the photocopying machines (most engineering textbooks were 4" thick and hence heavy!) and photocopy relevant material. Now one can search 24/7 online to find solved examples that are well explained (such as structurefree does!)....... Well done sir !! Then again, generations before mine used slide rules to design skyscrapers, so I shouldn't be complaining. To those of you that are studying engineering, it is a rough, tough and long road but well worth it. Tough it out; work and study hard and at the end it will pay off. Apologies for the long post. Keep up the great work you do 'structurefree" !!

To be or not to be.... that is the question

[@Josh-zk7pf]

so true man. I acknowledge how super lucky i am. Don't think i could've been an engineer if it weren't for youtube. KZbin has taught me everything for maths, I taught myself calculus watching youtube videos, all the way from even before precalc. you're very right, we have it much much easier. and i'm so thankful for it, because it gives me the opportunity to become actually try and become an engineer whereas otherwise the odds would've been stacked against me, such as in your times. It's much easier now but it's still very hard nonetheless.

The good thing with you guys is that you learnt more by going thru that

[@MOATHALSHIBLIvfx]

@@TheMrgoodmanners 100% true Yes we use KZbin to learn.. But we still weak..

thanks for the kind words and comment about units. I try to do both sets of units since I teach in the U.S. and the structural design codes are primarily in the FPS system with conversions to SI.

[@tysongill99]

I wanted to extend a personal thank you for this video. I'm studying for the October PE exam and a question on a practice exam asked to solve for a reaction using this method. Never heard of it, let alone used it. This video saved me what would have been days maybe weeks worth of time trying to study and understand this method from a book or online source that probably would have taken me days to find in the first place. Absolutely brilliantly explained, clear, concise, excellently done!

k=3EI/L is used when the beam has a pin/roller on the free end or where the beam structure terminates. In this example, the roller is supporting the continuous beam and a moment can be carried across the beam at the support. See the moment distribution method example 3 video, it has a beam segment that uses k=3EI/L.

Hey mate. Your videos really help all of us. They are probably the only thing that ensures we pass uni. And by "we", I mean the entire cohort of engineers every year. Appreciate it. We just don't understand, in this instance, how you got the zeros in the purple line at joint B. Could you please clarify?

[@marlam5478]

If you add the moments on each side of the joint B ( 52.083-3.456=48.627 and -40-8.627=-48.627) are equal. that means are balanced and you don't need to apply again the distribution factor. The iteration process finish when you get moment equilibrium at interior supports. better later than never :)

[@bradvincent2586]

@@marlam5478 Okay, can you still try to reexplain this? I don't understand. My professor kept doing the iterations until the distributions were negligible and small. What happens if you have seven iterations, do you have to keep adding up both sides of the joint til you figure out if they are even?

[@kezukivalentine5071]

Thanks Soo much for clearing this up for me it was really bothering me with the carry over

Hi Structure: I was wondering why your Carry Over for both parts of Joint B are 0 after 1 iteration? Im trying to teach myself this method and I cant figure this part out.

[@PG7II]

in the carry over row, how did you get the zero's at BA and BC?

[@ianwebber412]

how did you get the zero's at BA and BC?

[@folth9739]

it is default right?

[@oscareulatic2964]

It is a fixed support it absorb all the moments so the DF is zero.. If the end is roller or pinned support the DF is 1.
