I like how you went into witness protection halfway through the vid

Please keep the course going, I have the worst professor of life, and you're the best way to fix that problem! Please save us from bad professors...

Dr. Hanson, PLEASE keep the videos coming. You were a Godsend for statics and materials, but we need you for dynamics. I know it's peak hunting season, but if you could spare any time, we would be unbelievably grateful. You know when semesters end, and I need you this semester! I can't understand the words coming out of my professors mouth. He's a nice guy, but the accent is beyond strong.

Sir, I had no clue how to start this problem 25 minutes ago. You made it a breeze with simple and efficient explanations. Your videos are truly appreciated and have been recommended to all the engineering students I know taking statics and dynamics. Thank you for your time and effort to help those who are struggling with these concepts. Texas is extremely lucky to have a teacher like you who really cares. Best wishes.

Note: in the last equation of motion with theta, Dr. Hanson simply forgot to include the " + Nsin(30_degrees)" Happens to the best of us from time to time. Great work Dr. Hanson and I'm happy to support your channel and YouTube and on Patreon.

COME BACK!!! It's too hard out here without you! Please I beg on my knees, chapter 14 is ROUGH!!!! Please please please please please good sir don't leave us!

Had my first dynamics lecture today, you saved me in statics last semester, please do the same for dynamics. Much love from Turkey

Just an FYI he left out the normal force from his final equation (acceleration in the theta direction) but his final answer incorporates it and is correct. If he saved your grade like me and many others consider donating to his patreon. Thank you Professor!

20:45 I belive you forgot the radial component of the Normal force.
+Nsin(30)

[Rycamcam]

Thanks so much! May the sum of the forces be with you.

2:30 "you've got theta double dot, I dont know what that is" idk why but the way you said that has me laughing so hard

[adrianajimenez]

Please, continue making more videos for Dynamics. I'm taking Dynamic this semester. Your videos are saving me. Thank you for all the time you spend making these videos. I truly appreciate all the time you spend and the way you teach.

[WyrmholeWarrior]

You make a hard subject seem easy. I feel like you're more my professor than anyone else because I've been watching your vids for 3 semesters now. I used your vids from Statics, Solids, and now Dynamics. Unfortunately our class is going to pass where you are in this series after our first test. Please keep creating these vids. There's not a lot of solid videos for these difficult courses and you rock it!

[kerririddle]

You got me through Statics! Please keep posting videos for Dynamics they are a huge help.

[hazsyah]

Im taking exam tomorrow, thank you prof jeff for teaching me. How i wish you keep uploading this course

[utku]

Many thanks for the videos Jeff Hanson i watched all your statics series for my summer school and i got B+. Now im ready for the dynamics you teach very well

[TeaheanYT]

I'm taking Dynamics starting late January 2020, please keep this going! We love you! I'm finishing up the Statics course right now.

[burakyanic]

Sir! You saved all of us in statics course.I belive that your courses of mechanics of materials will save us.Thanks for everything.But we still need your help. PLEASE. Do not break to giving us hand.Please! Keep posting dynamics videos.

[kevinbeastly]

please continue with the course please please this course is really helping me pass (just like it did with statics) because i have a professor that is a good guy but does not know how to teach the subject at all

pretty please with sugar on top continue this course i have been able to find anything else helpful (and he is so far one of the best professors i have had in my college life so far)

[georgesadler]

DR. Hanson, thank you once again for another fantastic lecture and excellent example on the Equations of Motion in Cylindrical Coordinates. This particular example is very difficult to follow, however, I will review the problem to increase my understanding of the topic.
