Today, I was about to go to my statics class and I'm nervous as heck. Every time that I go to this particular class, I feel like everybody is going to devour me. To tell you honestly, I am not a straight A student. I'm below C and all of my classmates were A+ people. My teacher is expecting all of us to at least understand his processes and somehow catch a glimpse of what he is trying to convey but a lot of us, under Cs, are struggling to make the connection. Perhaps, the intimidation is just there. I don't even have to be in the class to feel intimidated but his teaching style were based off of high expectations, fear, and intimidation. Today, I watched this video to quickly understand our next topic which is, of course trusses, frames, and machines, and it just felt like a safe place for me to develop my solving skills bc im not really good at those, the way he said, "don't be afraid" is like an assurance to me that I won't be left behind anymore, and I never got that feeling in a while. Perhaps, the fear was already placed since the beginning of the year and today, it just vanished. All because a guy that i dont even know said "don't be afraid", "i got you"... Im crying rn. *YOU EARNED MY SUBSCRIPTION, GOOD SIR!*

I'm learning more from your videos than from going to lecture 5 day's a week. My professor speeds through all the lectures and fails to thoroughly explain the tips and tricks to solving these problems. Thank your for your super helpful videos!

[Jojo-nhxc]

Your videos are so helpful! I usually have a lot of trouble in school but so far I have a B in my statics class. Thank you!

[zEre]

My new favorite youtuber!!!! You’re the best

[elmass]

A 6 minute video for a whole chapter. Can only be one man. Dr Jeff Hanson SIR.

[manuboker]

Wonderful Statics lessons!! really taking the time to explain the problems along with a good sense of humor :))

[georgesadler]

DR. Hanson, thank for a powerful analysis and introduction to Trusses, Frames and Machines in mechanics.

[markkevinganotisi]

I am so grateful that I found you sir! You're very entertaining in explaining the topic and I wish if I become professional CE I will teach this topic like yours❤️

[KachaBirbirsa]

Sir please came with determinency and indeterminency for static and kinematic internally and externally

[estiakahmed]

Another wonderful tutorial. Hope to learn a lot from you, Sir.

[strawberryyogurt]

going over my trusses knowledge before starting my solids course, i hope i can get an A!

[chrismarston]

I'm 5 seconds into the video and you have already written more on the board than my professor has through half a semester. You might just save my grade as long as my professor stops trying to fail me

[Rsalance]

These videos are great. Makes me wish I was taking statics so I could really learn this stuff instead of statics and dynamics together lol

[usagi]

Omg I'm learning more on a YouTube video than in my class

[JoseSanchez-seyr]

Took me a second to get the pin but I'll admit I actually laughed at how ridiculous it. Xfirst time watching and I feel like this guy is gonna make statics bearable

[نيني-قز]

When calculating the loads on the trusses, should they be calculated as KN or N, or is it permissible to calculate them with both?!

[Ashleyl-c]

I cannot be the only one that thinks Dr. Hanson's jokes are hilarious! Or maybe my sense of humor is broken 🤣

[bagusbudi]

Nice video sir, I have some questions going on in my head.

First is truss must be connected with pin support but in the real application like a bridge or roof, the joint connected almost rigid with numerous bolts or welding. Is it still considered as a truss when the connection using numerous bolts with a gusset plate or welding connection?

Second, the load must be placed at the joint. So, how about a roof when in case the load is applied to the truss member directly unlike a bridge that can use a diaphragm to transfer load from the road to the joint?

The third is, Is it okay to not cut the member as the joint module length? For example, I have 3 meters length bottom chord module in the drawing (the joint is on every 3 meters), but for saving working time can I use 6 meters module instead? (the joint is still on every 3 meters)

[lovescrubs]

Love your videos, but could you please make them louder? I have the volume turned all the way up on my machine and the intro and the ads always blast me in the ears in between vids.

[A_struggle]

but in steel structure some times the truss are welded joints, so in that case how it remains pinned??
