Who am I?
I'm Cherish! I currently teach Mechanical Engineering but I remember the days of being a struggling engineering student. Going to class, feeling confused and frustrated when trying to do assignments because I hadn't learned much in class seemed to be a regular occurrence.
I created STEM Course Prep to save today's engineering students from the same fate. I teach my courses in a way I would have liked to be taught... light on theory, heavy on examples.
Organization is key to learning so I also provide an outline of notes, equation sheets, and more for my courses so you can stay organized and create a great resource for each class.

Normal and tangential kinetics with angular momentum and work energy
Problem 15-108 from Dynamics 14th edition by Hibbeler
when the 2 kg bob is given a horizontal speed of 1.5 m/s, it begins to rotate around the horizontal circular path A. If the force F on the cord is increased, the bob rises and then rotates about the horizontal circular path B. Determine the speed of the bob around path B. Also, find the work done by force F.

Thank's for the tutorial, this was useful for me in enginering, didnt understand that one well at my linear algebra classes.
what IXX means
Last diagram
why did x become the hypotenuse?
Thanks you so much for this simple explanation
BEST VIDEO EVER! I have my static exam today and this was a really good refresher!
Thank u very much for taking ur time to do something very productive and help us students.. I wish we could have more of u .. thanks 🙏
Thx a bunch mam
Thank u so muccch!! that was quick!
I came back to say thank you after passing the exam
nice
You are Really Genius. I appreciate.
Thanks a lot .... Im very much grateful 😊
But I have a question. Why you didn’t care about height when you choose the F’s axis?
you are my savior, ma'am..... What a clean solution.
❤❤❤❤ excellent communication
I wanted to but the materials course is there any current coupon codes ?
Dear God thank you. I was doing this completely wrong. lol
Bought the thermo and fluid bundle, thank you for providing really great videos Dr. Qualls! Majoring in M.E. and want to specialize in Aerospace! A+ here I come :) Glad I found your channel which led me to your website.
That’s great! Thank you!
Thank you for breaking this down!
Glad it was helpful!
How do I determine which direction the Fac vector points towards? Ex: when finding Fx for the BE beam you put Fac as positive but how do I know it will be going to the right?
Thank you so much! my prof is terrible at teaching dynamics
You are so welcome!
I really wish that youtube allows me to give you more than one like. Straight to the point, clear, and simple explanation. Thank you so much
Thank you!
Thank you so much, you really helped me.
You're very welcome!
Wrong solution but right answer
Super helpful! Thank you!
You're welcome!
useless
unless i am missing some fundamental understanding, you have your ma opposing the applied u1. this doesnt seem correct to me. your descriptions of what is going on is very good but the sign convention is throwing me off of what is correct.
I solved it with up as positive and got the same thing she did
I think the signs on the EOM are wrong. Shouldn't it be m + f = k + c since they oppose each other?
I am very confused as to why the C normal force direction does not matter. Because I had my C as going upwards and that changed my answer to the question
I also do not get why the normal force at C is going downwards either?
thank youu!!! hope u r doing fine
what if I dont have it stated that x1 = y and x2 = y'?
I think you made a mistake when you calc area. the area formula is A= pi d^2/4 correct me if am wrong . Thank you for your effort
the only tutorial that goes into detail about actually solving a problem. Thank you so much!
You’re welcome!
Top!! Very well explained 👍
Ty so much mam.♥
I really appreciate the effort that you put here, I understand the state space form of equation just in one hour. Are you going to use MATLAB to solve this ODE system? I need this for my PhD analysis.
I am a happy student now :D
This video is great thank you so much! Hopefully you can do more in thermodynamics
You're adorable Dr.! thanks!
Great explanation. Thank you very much ma'am.
Thank you 🙏🏼 so much 😢 after all I finally got it
This is great thank you
extremely helpful, thanks
Thank you. Is this the Cascade representation? How would we do the Parallel especially if you can resolve a system into the form A/s+a + B/s+b using partial fraction decomposition
this is really straight forward, def one of the more underrated videos on this topic.
fire
Thanks for the vid boss
It would be so cool if my teacher actually taught me this before assigning homework
this is gold. thanks a million.
You’re welcome!
