Perfect, thank you John Fuller. I need to calculate truss members for a new roof and yours so far, out of many, has been the clearest explanation on how to approach it. I need to marry up force with steel spec now to select appropriate materials. You’re a star.
You are absolutely a top tier teacher! You are not here to prove how smart you are, you're here to simplify complex subjects and communicate with students,
Thank you so much for making this so clear! I was stuck on calculating the first internal force for a multi panel truss calculation for some engineering homework and this video completely cleared up all of my questions!
Bro I have looked everywhere on youtube and you are the 1st person to make me understand trusses i sent ur video to my friends as well. I got mechanical principles exams on monday
Thank you so much this is one of the best videos from the best passionate teacher ever I saw. God bless you, when I was in Kabul polytechnic university I love the structure Mechanic and the highest score was 100.in the test my score was never less than 95. When I came to the USA in 1990 unfortunately I didn't have my engineering diploma and I couldn't study to get a certificate any way I ending working in retail stores until now but my passion never goes away especially for this subject. I am continuing to watch more videos from this great teacher or professor. thanks, Millions.
Great video! Thank you so much. However, I did note at 7:32, force x distance gives lb*ft, not lb/ft. (lb*ft - often called ft*lbs is a measure of torque (aka Moment)). The cancelling of units at 7:51 on the right side of the equation is technically incorrect (one would actually end up with ft^2 in the denominator), but this second mistake negates the mistake at 7:32. Overall, an truly excellent video! Wish my instructors would have had your teaching skills!
For me this was a great review of the material that I long forgot or haven't used and as was previously said it was much better than the way I was taught in my Engineering class. Thank you
helped me a lot, i had to search how to solve this type of problem in another language cuz in the monkey island i live in no one is able to explain it properly. thanks dude
Thank you so much 🗣️💯 but problems for me with these is when or how to use soh cah Toh and witch one would be best, was just wondering if you have a video explaining this. Would mean a lot 🙏🙏
Why is it that the calculation uses a roller applied force (single vertical force) when in implementation the point will not be allowed any horizontal movement and so both a vertical & horizontal force will be applied?
God Bless You! I am not an engineering student, but I am understanding how the answers are obtained. Sent this to a student struggling in Structural Analysis. Do you write/publish on this topic? Please let me know!!!!
Hello, I might be mistaken but isn't it tension when the arrows point outward on an FBD? Tension is pulling apart, compression is squeezing it, that's how I remember it.
@@Livenewme yeah I know, just felt it was necessary to point out for others who might not clearly understand the difference between tension and compression and how the relate in mathematical terms.
It’s actually how the member reacts to the forces applied to it. Since The joints connected to it pull it outward (tension) it has to oppose the pulling forces, which is why the arrows point in. Similarly for compression the joints are pushing the member in, so it has to push out away in order to balance the compression force. It’s been a year but I hope this clarifies it for you lol
@@Unaboner I mean, you're talking about Newton's Third Law which makes sense. Still, it should be what the type of force is upon the member not vice versa. Your explanation is still valid and I always saw how it could go both ways. EDIT: This was the case in PLTW courses, might have been different for other instructors. I had to do this in high school. It did this in 10th grade Principles of Engineering (PLTW). Of course, variations can occur with different curriculum.
Please could you tell me What does mean tangent envers ( 7.1) and how change the dgree to convert into angle by this equation ( force tangent =R*theta) Tanks
WOW, I had no idea it was this complex. I'm needing to build a Timber Frame Queen Post Truss w/Purlin and rafter design using a 12/12 pitch. The span would be 24 feet. It will be going on my 1850s 2 story Hand Hewn log home. Half of the second floor to be used/the other half open to below. Looking for how big of timbers I need using Tulip Poplar/white pine or ???. Thanks :)
patterns in math are crazy. Notice, if the truss was symetricl, it would have been 75 for the force, but since it is not, both forces are a difference of 4 from 75.. 71, 79. I would have to try another problem to see if this is a legit pattern, or just a coincidence
Does anyone know why 150lb is placed at joint C? Normally should not the weight be put in the center of gravity? Since the distances AC and CD is not equal I don't think C is the center of gravity.
I'm 78% sure this is a result of a hacker/account phisher hired to promote a culture of despicable behavior and generally lower the quality of the comment section and therefore the platform. 22% that it's an authentic troll without the mental capacity to add to the conversation. This video was excellent.
This is possibly the best video on engineering I have ever seen! Why can't my teacher teach like you?
i agreeee
This was taught much better than what my Engineering teacher taught. Very new to stuff past algebra 1 since I'm only in 10th right now.

I love the way you keep track of tension and compression. I could never get those right.
**** I love you, you just helped me out alot with this ! You should get a raise for this ! Thanks again for the explanation !
Best Video, please do Beams (UDL, VDL..) Pullies, and more..
Best explanation ever👍
This video saved my ass in an exam. Thank you so much!
Excellent explanation. ❤
Greeeeeat ❤
Such a great job presenting this material! So clear. Thank you.
You'r Amazing really you help me as good as possible thank you
Thank you so much, I wish that I see your video earlier. The best one so far.
Glad to help!
Thank you vary much dear! This is possible the best explanation on engineering I have ever seen. Why can't my lecture theach like that? 🙂
Hello, such a good video. Rcommendable. Just need clarification when indicating the tension or compression. 18:10 Thank you
This has been extremely helpful. Thank you so much!
perfect!! thank you for the video
Better than my Mechanic doctor 1000 times, Ty Sir ( Today Is 1/5/2022 ) ❤🔥
very clear explanation
What if we remove the king post causing compression forces in the upper chord and tension in the lower chord, how would this effect the formula
thank you sir, can i ask what application are you using to make this presentation?
Thank you so much 🗣️💯 but problems for me with these is when or how to use soh cah Toh and witch one would be best, was just wondering if you have a video explaining this. Would mean a lot 🙏🙏
This was quite helpful! Thank You!
How do the reaction forces change if the supports are on the side of the truss?
This is so helpful.
Thanks bro
Why did you flip the force of Fab. doesn’t negative mean compression?
Thank you so much for explaining
Great job!
Im taking this in 9th and I don’t even know trig yet, but this still helps a lot!
Why is it that the calculation uses a roller applied force (single vertical force) when in implementation the point will not be allowed any horizontal movement and so both a vertical & horizontal force will be applied?
Awsome! I totally forgot how to do this! Thanks so much

It's a easy thing to overlook you can fix this by just doing the opposite value of your answer

Glad I could help!
Can I ask how do you get a 35 and 32.4 sir??
I thought in compression the arrow was supposed to be pointing towards each other while in tension away from each other

What program did you use to make this? Nice work
Marcus Evangelista I used good ol' PowerPoint, along with the animations to help clarify things a bit
Moment calculation - units are not pounds per foot, but pounds x feet = foot-pounds.
