Statics: Lesson 49 - Trusses, The Method of Sections

[@joreilly]

I was sweating until the very end when he said REMEMBER - DO NOT CONSIDER THE MEMBERS YOU DON'T CUT. Jeff, you solved about 10 years of me hating this method with that statement. I've always screwed that up and over-complicated my problems.

[@SuperPenguinpenguin]

This is huge. I was so confused why he ignored EG in the sum of Y forces eq.

[@solomonmule3414]

it was the same with me

[@martinAbC]

​@@SuperPenguinpenguin I made the calculation later for EG, and it's equal to zero. But if there's zero reaction, why even have a member there? What's the point of having a structural member with zero force? Why not just remove it then?

[@EsotericWizard]

@@martinAbC for loads -- ie a bridge needs to handle movement of cars, wind, etc. it's just that the current forces don't make use of the member, but it would have purpose in another situation

[@exploringhub011]

@@martinAbC Zero force member is given in a truss to ensure its internal stability, such that all the joints should be connected!

Hey Jeff, i wanna take this moment to thank you for teaching me statics. I didn’t know what’s going on in my statics class until my friend recommended me to watch your videos. Here I am at 4Am watching them for my final which is at 7AM. Whatever grade I get, it’s because of you, sir!!! Merci pour toutes 🙏🏿🙏🏿🙏🏿

Your watching his video at 4am when your exam is in 3 hours? Don't put whatever grade you got on him 😂 that's not fair I'm just joking, but seriously not sleeping and cramming is not a good idea

[@LeonKarni]

Hey Jeff, great videos! Really clear and personally, they l have helped me out a lot. So thank you! You have a small mistake at the end of the video Calculating HE (should be 3.54 or(2.5/sin(45)= 2.5*2/√2) not 3.34) this means that DE is an even 12 not 11.86) Hope this is helpful. Keep up the good work.

[@gp7493]

noticed that too! :)

[@caitlinreinecke9704]

Thanks for this. Thought my working out was wrong.

I was saying the same thing!!!!! Your right!

Old man Hanson, great sir, you are my saving grace for this semester. I wish you and your family a good life. Hope you're doing great

[@engineeredchannel5649]

Thank for the kind words. I need all the blessings I can get! Hanson

[@nathan8472]

thanks my friend, I take your greetings and bubble wrap it in my soul.sincerely, Dr. H

[@promisesebaka5122]

I never understand anything in class buy you are always my last hope and you never disappoint. Thank you for clearing all my confusions sir

[@sarahtarbox6621]

Your videos are SO helpful! I'm a high school teacher who hasn't taken a statics class since 2009, and when I started getting ready to add an engineering endorsement to my teaching certificate, I realized how much stuff I had forgotten! I wish you had been on KZbin back when I was in engineering school!

[@TheEntorm]

I am seriously so thankful to you Mr.Hanson, my static teacher is probably the worst teacher I've encountered and teaches everything hard for no reason. Times like these where I wish good teachers like you would be more common

[@vladimircastanon9682]

Another amazing video Mr. Hanson. I love how you went through each step and didn't over complicate things, I think that's what makes your videos so nice to follow along. Hats off to you sir you have a gift for teaching, thank you!

[@Charles-bz8kk]

best professors i've had in college so far? Hanson and Leonard.

[@farahaltanany2238]

I literally love you. I'm an architecture student and we have required structure classes that are kicking my BUTT. thank you for these videos they make my life so much easier !!!

[@oyekolaphilip3279]

Hii

[@debbiekalima4541]

when my lectures made me feel dumb your videos make me feel smarter all am saying is great job jeff really appreciate this

[@eliot327]

Studying for the FE rn and this has been very helpful as a refresher. Thank you.

[@alizekazmi3129]

I cannot begin to thank you!!! you might not read these but seriously, without a professor like you, I wouldn't be able to pass this class!! thank you!! truly.

[@He787878787787]

HE is 3.54kips compression - small error

[@undeada-man1920]

Thank you so much for these videos. I'm not kidding when I say that watching these last two have taught me more than my statics teacher has in 3 months.

[@FinchyTV]

relatable ngl

[@georgesadler7830]

Professor Hanson, thank for explaining Trusses and The Method of Sections with a massive example. The step by step process is very helpful for solving Trusses.

[@NiemanScott]

Jeff thank you very much for these videos. My professor is great, but he tends to teach a much theoretical style and doesn't go into the "plug 'n chug" as he says. You're a great supplement and I wouldn't be doing as good if not for you.

[@samparish7124]

So glad I finally found your lessons Jeff, thanks.

[@jaydenogilvie9512]

thanks so much for your contagious enthusiasm and for continually making my life easier with your memory tools and excellent teaching skills, definitely going to be the only reason I pass this class. :)

[@nomnom4346]

I just started methods off sections and this video summed 6subchapters very well. Thank you so much

[@JordanlPearce]

I don't leave comments but I've been sweating this topic and you're making me a lot more comfortable on it and easy to understand!

[@kevmcc9873]

I want his autograph. The reason I'm going to pass statics! Appreciate all your help.

[@SunnyVorn]

This made so much sense. Thank you so much Mr Hanson

[@DrJQureshi]

Great videos. Teaching truss analysis properly is crucial for young engineers.

[@nicolas13brito]

honestly, you are such a wonderful teacher, I am very glad I found your channel and I hope you have a wonderful life!

[@ezraclark1793]

thank you so much! I was so confused on how to sort out whether or not the members were in tension or compression, but this cleared it all up!

[@ehanbenjamin]

Thank you for the help! I am using your videos to study for the Architect Registration Exam. Very helpful!

3.34kip for HE should be 3.54kip, and DE should be 12kip.

[@musamohammed4491]

Yeah

[@malinanjana]

[@willpope302]

Incredible explanations thank you very much! The way you labeled what would typically be joint “C” as being joint “D” kind of bothered me lol, but regardless you’re the man!

[@andrewmorrissy3122]

Thank you jeff you explain statics really well thanks!

[@Subcritical96]

Thank you Jeff. Great videos. Calculation at the end should be HE=3.54 kip (C) and DE=12 Kip (T). You do have it set up correctly. Again thank you for the great videos.

[@pielditakau]

Exactly what I got, but DE should be in compression. Remember when you are substituting for HE to get DE, you put in -3.54 coz it's in compression. And the overall outcome is negative, so it's in compression.

[@pielditakau]

Hey senior @jeff, the value of HE is 3.54kips in compression whereas the value of DE is 12Kips in compression as well. It doesn't matter if you take your left as positive and vice versa. Thanks btw

[@drogones12]

Jeff, I got confused when you were solving for DE. It looks like force DE and 3.34*cos45 should have the same direction. so I am thinking the Fx force summation is 0=9.5-3.34*cos45-DE. Can anyone clarify this for me and much appreciated.

hey, sir jeff! thanks for making this kind of educational video. really helped a lot for me to understand my Theory of Structures subj. God bless!! CONTINUE MAKING VIDEOS!!!

man just want to let you know, you just explained what my teacher can't explain in a 100mins class

[@njis_recipes]

In the summation of FY, it should actually be in tension cos the HEsin45 has to move to the other side to become positive that is 9.5-7=2.5. 2.5-HEsin45=0 take the HEsin45 to the other side. It becomes positive. Check it again sir

[@simonabarisic4829]

Thank you for your videos. Hope I pass my exams.😊

[@NthabelengRankoe]

So easy thank you Jef

[@ElPsyKongroo]

As a cheme major learning post grad on trusses idk what they were on about with mechE being the "easy engineering". It may be easier to understand conceptually but theres about the same amount of problem solving.

[@farisharoon9837]

Do you have anyone you’d recommend that makes videos for Fluid Mechanics ? I found your Static videos so good , went from failing badly the first few assessments to smashing the rest .

[@muhammadzulfaiz3255]

I hope I will pass my exam next few days....thank you so much sir

I would really appreciate it if you could make a video about how to convert uniformly distributed loading on the truss to point loads. T-T
