The reason you are not enjoying school (Engineering)
zhlédnutí 1,1KPřed 3 lety
If you are discouraged with your Engineering classes, or just plain bored, it is probably not your fault. Many teachers do not explain things well; they use big confusing words, unclear language, and many times seem to forget that we students are just beginners in this! I show some examples of bad teaching so you know what to look out for

Dynamics Problem: Particle Kinetics - Radial & Transverse Components - Problem2
zhlédnutí 1,7KPřed 4 lety
Similar to the last problem except that we don't initially know the angle of the velocity and acceleration so we can't take advantage of it.
Dynamics Problem: Particle Kinetics - Radial & Transverse Components - Problem1
zhlédnutí 971Před 4 lety
We've looked at a problem like this before in the Kinematics section; we know the direction of the velocity and acceleration vectors, we can use this to more quickly solve the problem. The only new thing with this problem is that we have forces and Newton's 2nd Law
Statics Problem: Friction, Tipping, & Slipping - Problem2
zhlédnutí 2,7KPřed 4 lety
Perfect problem that shows how tricky and conceptual this chapter can get. Remember to visualize what your math equations are describing, don't just blindly "plug and chug". These problems can really help build your analytical skills [VERY IMPORTANT]
Dynamics Problem: Particle Kinetics - Normal & Tangential Components - Problem2
zhlédnutí 555Před 4 lety
This problem is a basic Normal and Tangential problem. The only new thing you might want to put on your radar is using the derivative of the path equation to figure out an angle. We then use this angle to split the forces into components. We also use the radius of curvature equation and the equation of the path to produce the radius of curvature (needed to compute the normal acceleration)
Dynamics Problem: Particle Kinetics - Normal & Tangential Components - Problem1 (Gravitron Problem)
zhlédnutí 921Před 4 lety
Without a doubt you'll see at least one of these types of problems in your Dynamics class. It involves an object being spun in a circle at a great enough speed such that the static friction force is able to hold it in place and prevent it from sliding down (or up). This is the working principle of the "Gravitron" carnival ride Gravitron: en.wikipedia.org/wiki/Gravitron
Dynamics Problem: Particle Kinetics - Rectangular Coordinates - Problem2 (Cords and Pulleys)
zhlédnutí 553Před 4 lety
This is a good problem that has a lot of concepts in it, the most important one being that "negation" you must do between your Cord equations (which are based on variable "s") and your FBD equations (based on variables "x" and "y"). Overall with this problem, you'll get experience with 1) Free Body Diagrams 2) Using Kinematic Equations 3) Writing Pulley Equations 4) Writing Cord Equations 5) Us...

Thumbs up if you are watching this to understand orbital mechanics
did you make it automatic
This is literally the best video I've ever seen!!! Good job!
Okay, I said that before watching the full video, but I just got to 10:10 and my mind is blown, this is better than the best
I'm not even sure how I got through physics 1 without knowing the fundamentals this video is instilling in me now
Agreed, well said
Beautiful video
Nicely explained
Thank u sir for clear explanation but mixup hindi please sir
Incrível!!
DUDE I JUST WANTED TO TELL YOU HOW MUCH I APPRECIATED THIS VIDEO 10/10. My college professors would just explain it the same over and over again and it never clicked with me why I would chose on method over the other. Like how you explained why u-sub would drive you in a circle and thats when you should be using the half angle identity instead. It finally all clicked together for me and I cannot thank you enough. LOVED THIS <3
So glad it helped :)
😢😢
You have problem?
I cant believe i’ve paid 500$ for this class, and this guy just broke it down in 15min, I really hope you are a teacher, might never need this again but im subscribing just to encourage you
That's very kind of you :) Best of luck
WELL SPOKEN
what a greeat video ....thanks alot
Why do we assume FAC is 480? Because it appears in both equations? Is it just because it lets us solve both or is there another reason
You are a freaking unit. I’ve spent an embarrassing long time to understand this. I really wish there were many more videos like your in the world.
First video that genuinely helped me understand this. Thank you so much!
thank you this was very helpful
thanks!
literally my savior couldnt find anyone explaining this method well
shouldnt the moment be positive and shoot upwards?
shouldnt the moment be positive and shoot upwards?
OMG!!! I've been looking for this the whole internet!!! You're an amazing tutor.
As you did a fit, then why not matching the mapping between motor control angles and position on the image plane, by identifying numerical parameters upon a calibration procedure that does not require measuring lengths in the real world?
Might just need a little more videos for CZcams to recommend your channel 😮
can you explain the last step where you got the final answer? the part where you did the matrix
thank you, this helped a lot
nice basic stuff, need to learn basics to understand Coriolis and Euler and centrifugal forces for earth dynamics... I was told centripetal and centrifugal are terms used for 'fictitious' forces in non-inertial frames (ie moving in circles) .... but the concept of normal you have shown seems non-fictitious to me makes perfect sense and I see it used to define Eotvos effect (an up-down force) in the context of gravity on an oblate surface....... the Coriolis force is considered 'fictitious' says on Wikipedia... but I think it too is an effect... related to independent movement on a non-inertial rotating surface... sorry if I am confusing people! But Thanks for keeping it simple!
I came from an entirely different background and this surprisingly doesn't look scary at all. My sincere thanks and gratitude.
Perfect inspiration for me halfway through my Mech Eng degree. Top quality video, keep it up!
LIFE SAVER, THANK YOU!
Easy to understand! Thank you!
How did we find the value of 32.2
Its the english unit version of gravity. 32.2 ft/second^2
Love you brother u deserve million of subscribes
neat explanation, tq sir. leant alot
Best video I’ve found to explain why the normal force is used in Frictional Force analysis for non-slippage and slippage conditions. Thank you.
Do applied force be greater than Maximum friction force , in case of tipping? Because the body does not move , please explain it?
Sprite!
Thank you for this great video. What exactly is the unit of the acceleration a = sqrt((a_r)^2 + (a_theta)^2) if a_r is in m/s^2 and a_theta in rad/s^2? Timestamp: 10:25
I'm asking for the book you got the questions from
Hibbeler is the author
Nice video... Perfect explanation!
Thanks!
Does each instant in the motion of the particle have its own unit vector?
It's more like this: For each instant of motion, the particle has the tranverse and radial unit vector, whose magnitude is a constant of 1, but whose direction changes
13:38 why is this the equation (defined from tipping) that has the relation for P & T that we would use for defining if it slips?
Upload problem of 200 puzzling problems in physics.... Ss krotov please... That may be required for olympiad or olympiad foundation
Helpfull for jee exam thx
Good but one mistake. When this box rotates, the direction of friction must be changed.
Woww I found it hahaha
Congratulations!
at 10:16 I couldn't understand how it is perpendicular because magnitude of r_i and r_f are equal and 1, so isn't that angle being 90 degrees geometrically impossible?
I think i get where you're coming from. The answer is that the very small angle in between r_f and r_i is soooo small (much smaller than the unit vectors of 1) that the dr is coming out perpendicularly from the r_i It'll help if you draw this one out yourself. Take an entire sheet of paper and do the vector addition: r_i + dr = r_f Make sure you draw r_i and r_f to be very big (relative to the very small angle d_theta). I think you'll see the 90 degree angle. Let me know how it goes
This is insanely accurate to my experience as well, many teachers seem to be forced to teach rather than have a will to teach. A few years in and I'd say it's around 2/10 teachers that actually break things down and explain in a way a student can understand. The rest are varying levels of no explanations to bad explanations. Or the classic of obligatory(and expensive) literature which is written in such complex and ambiguous language that you need to have a fundamental understanding of the entire course to even begin to grasp the book. It's literally pushed me to the limit of burnout having task after task thrown at me with no guidance and lectures that barely explain the subject. Been looking at a few of your videos and really appreciate your thorough explanations, hoping it'll make it easier to see the whole picture.
Thanks for your comment, what eng major are you in?
@@eng1048 Not sure what the exact title would be in English but the rough translation is mechanical engineering with a focus on material science.
Just finished the video series for dynamics, this was awesome! Super helpful for my midterm coming up, Thank you!
Good luck friend, as you traverse into the Valley of Darkness. Be Strong
Great explanation on transverse and radical components! It helped me out a lot. I wish you explained what you mean by "True velocity is always tangent to my path" though. In a different question (same principles) how would I determine the direction of the yellow arrow (drawn at 13:18).
To your first question: Remember, speed (velocity) is an instantaneous quantity. I can have one speed at one instant, and another speed at another instant. Even if my speeds are the same at two different instances, if you are facing (imagine you are driving a car on a curved path) different directions at those 2 different instants, your velocity (which is just speed but incorporating the idea of direction) is different between those 2 instants. So the DIRECTION of your velocity at a specific instant is basically "which direction am i facing/travelling at that instant". Think about this a little bit and hopefully the idea that "velocity is tangent to the path" will become more digestible. Your second question: If you knew the transverse (r times theta dot) and radial (r dot) components of your velocity at that instant, you can draw a right triangle and use the inverse tangent. Keep in mind that components of a vector do that tip-to-tail vector addition thing to add up to get the resultant vector. Thats why you can draw that right triangle between the radial and transverse component and the true resultant velocity vector. Once you drawn that right triangle, you can use the inverse tangent to get an angle for the actual velocity vector.
