Use the Method of Joints and BASIC Physics to Analyze a Truss | Statics

[@icelordotis]

This was amazing, I find that many other videos just talk about tension and compression without any reference as to whether they are talking about forces acting on a member or forces that a member exerts to oppose external forces, which led me to be more confused than when I started. You've reaffirmed my initial intuition of what each force represented. Thank you

[@INTEGRALPHYSICS]

the forces ON the beam vs the forces BY the beam is always a point of confusion, largely because different instructors / texts handle it differently, sometimes without being expliccit about what they are doing.

[@MichaelLaprarie-p4c]

Thank you for making the best video I've seen on this subject. Sharing with my students tomorrow. 🙂

[@vladimircastanon9682]

AMAZING VIDEO, I love the way you explained tension vs compression of internal forces at the end. Hats off to you sir, please keep making more videos.

[@ivoryas1696]

Well _this_ channel seems *_thoroughly_* underrated... Might as well sub!

[@INTEGRALPHYSICS]

Welcome aboard!

[@HelloJamesBond]

Brilliant explanation on method of joints. I could never quite get this in my structures class but now I've got it, cheers.

[@finaltouchautodetailingllc]

I enjoy learning from your videos

[@INTEGRALPHYSICS]

Thanks! This one was fun to make.

[@GryffieTube]

Excellent video, thank you very much indeed. I thought I spotted an error earlier but it was me! Excellent explanantion, thank you!

[@vaa7236]

perfect video really the only video I could understand anything off of about the method of joints I just didn't understand how you used the Pythagorean theorem to find the force in beam BD

[@INTEGRALPHYSICS]

If you know any two sides of a right triangle you can solve for the 3rd using the pythagorean theorem.

thanks your voice sexy btw @@INTEGRALPHYSICS

dude it makes so much more sense now how the fuck did I miss that !!!!!!!!@@INTEGRALPHYSICS

[@squadman3376]

Thank you. Been framing houses for a long time. Those geometric wobbly trusses do an amazing job when properly braced, blocked and sheathed. Geometry rules . !

Buddy of mine was a framer, he always said the walls were like a house of cards till you put the roof on.

[@smokingsara001]

Sorry, I don't get how you got 33.7 degrees. 2^m and 3^m equals 33.7 deg?

[@INTEGRALPHYSICS]

arctan of 2/3

[@ralphbroeils1760]

It's all force/load equilibrium.

[@babulsy6460]

Excellent 👍, 🙏 from India

[@INTEGRALPHYSICS]

Thank you!

[@eriedului]

Is member bc a zero force member?

[@lhote8988]

Super. Thanks.

[@stephencrown6697]

Thank yiu so much Very helpful God Bless you

[@INTEGRALPHYSICS]

You are most welcome

[@relaxo6209]

Is there a video showing the forces in bow's notation?

[@INTEGRALPHYSICS]

No. Great suggestion though.

[@terezamaskova9699]

How did you get that F(ab)= 90.1N ? I’m getting AB= 66.1N

[@hunorkosbor9831]

Your calculator is in the wrong mode. I had the same problem and I asked chat gpt which gave me 90.1N

[@sarahdecampo6937]

@@hunorkosbor9831which mode should it be in!

[@alexts94]

Immensely helpful, thank you

[@INTEGRALPHYSICS]

Glad it was helpful!

[@SaleenJ]

What if AB is plastic and BD is steel?

[@INTEGRALPHYSICS]

that wont change the calculations, but it will affect which member is likely to fail first.

[@erinbentson-er3ki]

First

[@PavelBuravtsov]

it is very hard to imagine in my mind how the wooden beam can actually stretch like a spring and having a tension force...

[@dandelareye5233]

The molecules that make up the wooden beam do not touch but are instead held by intermolecular forces of attraction. These intermolecular forces are the results of attractions between charges. The molecules of the wood are similar to two magnets that are attracted to each other. As you try to separate the magnets, there comes a point where there is a gap between the two magnets but they are still close enough to be strongly attracted to one another. This is how the wooden beam can "stretch". Although the "stretches" are molecular in nature.

[@ramlalgajoo2722]

Not very infornative

[@stephencrown6697]

Not true. Quite a lot of help in this video
