i just found your youtube channel by mistake, i cant believe you are giving out all of this great content for free, you ARE a great teacher

[ignaciovaldovinos]

Can't express the gratitude Professor. The great service you are contributing to humanity. Passing your knowledge to the next generations. Thank you!

“Babe wake up, Jeff Hanson dropped a new Statics video”

[djtfan]

Great to see you're still active! Will you be working on your thermo playlist any time soon?

[georgesadler]

DR. Hanson, thank you for an excellent lecture on 2D Equilibrium of a Particle With Springs. I liked these problems from Engineering Physics One. Dynamics also has problems that deals with springs.

[ashtonaranda]

there's something so meta about using these videos to review for my Statics exam in your class

[ginobenedetto]

Professor is there any word on if you're going to finish the thermodynamics series? There's a few videos already missing I believe five and six as well.

Are AB & DE not ropes? Why cannot the hypotenuse (AB or DE) change? Can they not extend in tension when the spring retracts?

Haha, "konstant" actually _is_ the Swedish word for "constant".
The difference is that we emphasise the final syllable instead, and pronounce the A vowel as more like "ah!", so it sounds kinda like "konst-AH-nt".

passed statics class because of you. Thanks you legend.

Need to retake statics next semester . What are the major things that cause students to not grasp the material ( obviously practicing the problems ), but is it weak fundamentals, certain topics not fully grasped that build on each other, etc . ? I want to practice over break

[kevcopo]

Statics seems a lot easier than it does at face value. Simple steps just knowing what to do is the hard part.

[regulusblack]

I am very thankful to you. I feel that I can really understand this difficult subject. I have Simple question, how do I get the angle out in a minute 4:10 I mean how did you know it was 8

[hassanramadan]

Sorry Dr jeff
Tension in the spring according to θ=45°
But equilibrium equation at θ = 56.3°

[vladimirstamenov]

In your book, page 55, where this problem is depicted - Point A and Point C are not on the line, neither are D and F, so the problem doesn't look like this. I was very confused about how to go about solving it and felt bad for looking at the video, because with those lines you cannot figure out the angles and lengths in this way.

[haliltarbak]

10:04 is it not supoosed to be calculated as 220? the spring is being pulled by each side.

[ibraheemmonks]

Hi Jeff, I'm working through your thermodynamics videos they are fantastic, please can you make some more, for example on ideal gas law. Many thanks!

[radiatedracer]

Hopefully you can answer this question. I cannot find a video on this. I have a combined loading problem that includes an internal pressure. So I find all the states of stress, only thing it doesn't have is an axial force, and I find the hoop, longitudinal stress, but I don't know what to do with those afterwards? where would I include them to go into von mises stress? in the text and any online videos they don't really show a problem like this, they just have the hoop, longitudinal stresses, and then call those sigma1, sigma2.

Hi man first time on your channel.
Do you also make videos on JEE MAINS and Advanced???

I can see a major misconception of interpreting that the 12” stays constant. Which is what I assumed incorrect.
