Most underrated youtube channel holy shit
😅 Thank you!
Pls,are you going to upload more videos on thermodynamics, I really need your help,I had (A) in dynamics and all the glory be to you
I am, but not until the start of October. Currently, it's very busy for me and I don't have the time to work on them. :(
@@QuestionSolutions Just letting you know that I really appreciate your videos.
@@idolbob Thank you very much :)
Pls turn on subtitles :') it really helps
I don't know why some videos have it and others don't. I will look into it.
Would you please make the video on strength of materials and fluid mechanics?
Yes, it's on my list of videos to make 👍
Sir, please continue this series......
I plan to, but things have been really busy these few months, far more than what I expected. I will start it up soon.
amazing! TY
You're very welcome!
Thankyou for the video Sir.
You're very welcome!
Very helpful 👍👍
Glad it was helpful!
This presentation was great, I have some question. Could you tell me about this application or program in video that you use. Thank you.😊
Thanks! Illustrator for the drawings and after effects for the animations :)
Thank you!
You're very welcome!
Hi, I was wondering if you could share tips for Mechanical Engineering majors and tips you use/used in school to gain such profound knowledge of the subjects. I purchased all of the textbooks and try to stay 1 week ahead of the class, but some topics are truly difficult. I am taking Thermodynamics 2, Electrical circuits/systems for Mechanical Engineers, Solid Mechanics, Fluid Dynamics, and Calc 3. I was stuck on shear force and bending moment diagrams for solid mechanics, and your videos helped me with that a lot. I try to attempt all of the textbook questions, which is very very helpful but consequently very time-consuming. My goal is to continue with my undergrad research and graduate with a ~ 3.8 in 2 years, and hopefully be admitted to MIT/Stanford graduate school. You have helped me a lot in the past with your videos, so I would love any advice you have for success.
You seem to be doing pretty much everything I would do. What worked for me when I was doing undergraduate, and really, anything further than that, was to create a schedule for my self. So if you have 5 or 6 courses per semester, you dedicate a single day of the week per course, leaving 1 free day to redo anything you're struggling with. This works for some students, and for others, it might not. It just depends on your learning style. Also, you don't have to do all the questions in a chapter, rather, do a few easy ones to understand the basics, and then skip to the hard ones. Usually the last 3 or 4 questions of the chapter will let you know if you grasped the concepts properly or not. Lastly, your school will give you access to past exams, so time yourself and complete them, it's very helpful :) Best wishes with your studies!
@@QuestionSolutions Sorry for the very late response, but thank you very very much for your advice. I will implement your advice! ps: your videos has helped me have an average of 100 in Mechanics of Materials so far, especially the statics review ones! I actually found about you from a professor for one of my courses who listed your channel as a key resource for success
@@rehanrashid9296 Wow!!! You might not know this, but your comment made my day. Other professors listing this channel as a key resource is such a nice thing to hear :) Many many thanks for letting me know!
hi there, i was wondering is there any tips to break down such complex question problem that is not only written without images/picture but also have data that spread throughout the question problem (such value, clues, assumption, and etc.) that you can turn into a simple known data just as you show in the video there? any tips even a little one will be appreciated🙏
I think for most problems you face, it's super helpful to draw a diagram. It doesn't have to look nice, but something that you can actually look at. Then you label everything given to you in the question. If the question involves 2 states, so for example, before a reaction vs after a reaction, draw 2 separate diagrams. Label initial conditions on the first diagram, and then the final conditions on the 2nd diagram. That way, you have a visual representation of what the question is offering you. Next, think about what the question is asking from you. Without thinking of numbers, think about how you can get to the answer it's asking for. Think about the equations pertaining to your question, what can you use? Then you can start step by step. Sometimes, you will make a mistake, but that's perfectly fine, then you retrace back to the step that went wrong and go down a different path.
All of what I said can be helpful, but the most helpful thing you can do is to practice as many problems as possible. Try to do a few easy ones at first, then a few medium ones, and finally a few hard ones. It doesn't have to be a lot, solving 5-8 questions per chapter should give you enough insight to solve other problems. I don't know if that's helpful to you, but the best way to become a master at these problems is to try and do as many of them as possible. :)
Hi your videos are very amazing. can you please tell me which
software/s do you use for animation and editing
Thanks
I use after effects for animations and illustrator for the diagrams.
@@QuestionSolutions Thanks
@@QuestionSolutions Will Adobe Animate work or After Effects is far better?
@@sefofiwilliamlebea4071 I think either is fine. Maybe try both and see which you like better 👍
@@QuestionSolutions Thank you soo much. Also for helping me get through my Dynamics course.
