I really appreciate your videos, you literally saved me on my third semester and i have been following you ever since.Keep up the good work!

[donwooss]

God lord i wished i was in your course when i was learning this. You're awesome.

[rohitbyassherwan]

U have really helped me through this video.Thanx for that buddy

[peterdurand]

Finally got the answers. AI +40, AB +67, AH +24, HG -75, BC +40, BG +38, BH -27, IH -89
CG=0, CE +40, GE -45. Fingers crossed.

appriciate your work! can you at some time share a video about arch shaped truss systems?

[sikanderali]

I am not sure but can we identify CG as zero force member bcz if we consider joint D then DF is zero and then at joint F force in member CF is zero and at joint C force in member CG is zero.

Hi, I solved the force diagram using the method of joints. I came up with slightly different results. BC=0, GB=28, GH=-78.

[skept]

when analyzing member Ngc can i consider joint C instead of joint G? whats the premise of using joint G instead?

[abegailbartilet]

please, i need a video tutorial for maxwell's diagram

+strcuturefree Sir it was a very nice video, just at the right time I've gotten this video. You're awesome sir as well as your presentation...thanks, keep up the work & help us ^_^ & thanks a lot for this awesome video ^_^

+strcuturefree @structurefree hey man can you make a new playlist for statically indeterminate structure videos please?

[ntonyjaime_]

Can you explain how you got the 2 to 1 and 1 to 1 ratios please.

[paulaableto]

hello, THANK YOU FOR THE TEACHING, PLEASE HOW DID YOU GET YOUR ANGLES EG 1/ROOT 2

[carolinamendez]

Question: GH a compression? if so why are you calling it a negative value when you are solving for FG? shouldn't it be +?

[emrage]

Checking determinacy, isn't it Members * Equations i.e. 15*3 > 18 reactions


3n > r - can someone correct me if I'm wrong?


Or even point me to a reliable video where it's explained properly! Thank you

[jameshibbitts]

I hope you have a patreon when I graduate....

Also, any way you could upload your work on your blog? I screen shot it using OneNote but it would be way easier to just import it

[paulpalm]

Couldn't you find Ncg by identifying zero-force members?

[edwardarakelian]

I would really appreciate if anyone can answer my question. Can we use this method if we have an indeterminate truss?

7:57 it has been confirmed that Mr. Structurefree is part cow

[haseebahmad]

what is the role of checking the determinacy in this problem?
