The best thing is that I was watching this tutorial with smile on my face, with no expression and feeling of confusion, knowledge and humour in one, learning couldn't get any better
I love Mr. Hansons demeanor when teaching. His tone of voice feels like him patting me on the head saying "it's going be okay, we're gonna work it out, you got this." 😆
Oscar Slute I didn’t get a BS degree in engineering, I got it in sustainability. I didn’t take statics, I just learn it in all my higher level classes. I don’t have course space to take statics.
going into my first year of engineering, taking the summer to pre-study the courses that fellow engineering students said were very difficult before i take them, consisting of statics, calculus 2, and intro physics. Thank you for the continued amazing videos. Mark my words, im gonna finish first year engineering with a 3.7+ gpa!
Alright, YOU ARE THE BEST AND COOLEST PROFESSOR, understood everything AND the jokes make it even better, kind of like the same self monologue I have when I study 😂
I never thought that vectors will be included for my lessons as a first year meteorology student, and I am also stuck with such problems. Thank you for this vid!
I thought of another way to remember the equations: "I got a sick sister, cuz; with THoes (toes) and PHIet (feet) too" SIC -- Sin Cos for X SIS -- Sin Sin for Y COS -- Cos for Z THoes and PHIet -- angle theta goes before angle phi (theta is alone in F_z) Hope this helps.
Was messing around with trig and vectors just because I had a thought that you could use both of them together, I tried but was a lil confused. however the door/plane helpful. after looking at it that way i immediately understood
@@Error-br1uy it’s a weird one to get your head wrapped around at first, but the main thing is to just follow your rules and think about things logically in a step by step way. I think statics looks scarier than it actually is because once you start breaking things down things start to click.
@@Error-br1uy Hey, that happens…. And it’s only one assignment. I’ve made 35’s on midterms and still passed the class. What was the homework assignment over? Moments and force equations?
Question, so you know how in 2D system, Fx is not always sin but it can also be cos and Fy is not always cos it can also be sin. Here in 3D system will be Fx always be Fcos(swing angle)sin(thetaz) and Fy be Fsin(swing angle)cos(thetaz) and Fz be Fcos(thetaz) or there situation that just like in the 2D system they can change??
12:18 im trying this equation for a stupid statics problem that looks like a green metal thing stuck to piece of stone. For some reason... the Fy and Fx values are switched... sorry if im not making sense
Sir can u give me example of 3 components of a vector in our real life. 2 D components we can understand e. g. A box kept on inclined plane. Weight can be resolve into 2 components. Mg sin θ and mg cos θ
I figured out whatF subset h stands for!! It is the hypotenuse of the imaginary door which will be the vector projected on the plane looking down from the helicopter to determine how far it swung from the X axis.
Is there a proper term for these "Blue Triangle Equations"? I could've sworn I've seen these in my multivariable calculus textbook but don't remember what they were called.
In conclusion, he is the best instructor that we will never have :( I got a perfect score on my test by seeing his videos

“Okey I’ll fix it” was so funny, thank you for this great and easy explanation 🤍
lmao i read your comment the moment he just said it
This has been the easiest explanation of 3d vectors wow

@@jacksonr260 favorite comment of all time!
@@1234jhanson Woohoo! It's 100% true!
im watching all of these this summer thank you! I'm an environmental engineering grad student
Bruh how do get a BS in engineering without knowing statics?

I'm also in my first year of engineering and doing the same! Taking breaks to prestudy, I wanna be successful.
Thank you, Statics is a prerequisite for most of my engineering classes and I want to do well. I owe you my engineering degree.
Im 38 and loved math. NEVER EVER has it been clearer to me! Golden stuff!
Alright, YOU ARE THE BEST AND COOLEST PROFESSOR, understood everything AND the jokes make it even better, kind of like the same self monologue I have when I study 😂
You are a Legend! Teacher never explained this well and I've been stuck on a problem with a blue triangle for the past two days. Thanks Jeff
Thanks so much for working hard. I'm going into Civil Eng Technology soon and I just want to get ahead a little. You're awesome!
THANK YOU SO MUCH, I spent an hour looking for help to do a question like this and I am so glad I came across your video
I never thought that vectors will be included for my lessons as a first year meteorology student, and I am also stuck with such problems. Thank you for this vid!
Happy tears. Thank you! You have no idea how much this has helped me x
Dr. Hanson , you are amazing. Love from india.
with you teaching , I Wouldn't miss a class even if I'm sick...
Classes would be something to look forward to
Oh my god, thank you for deriving the F_x, F_y, F_z, & F_H equations the way you did! The other equations make sense to me now. Liked & Subscribed.
I've been looking for a good explanation of this for days and this is the best one I found
I finally understood my homework, thank you so much.
Damn, no wonder America has good engineers...
Man you saved my life. My lecturer was trash!!! barely understood statics. Damn i wish i was your student.
Phi has always been the angle from Z for my classes so this weirds me out a bit, but it was a good explanation.
I thought of another way to remember the equations: "I got a sick sister, cuz; with THoes (toes) and PHIet (feet) too"
SIC -- Sin Cos for X
SIS -- Sin Sin for Y
COS -- Cos for Z
THoes and PHIet -- angle theta goes before angle phi (theta is alone in F_z)
Hope this helps.
that was the worse ever sentence put togehter to remember this hahah
This helped me understand the concept of the parallelogram law in the 3D axis. Thank you
THank you for the best tutorial ever. Ive understood every word youve mentioned.
Thank U dr.hanson I am ur student from Malaysia
The best teacher ever 🎉❤
God bless u Dr Hanson continue helping students
What a lecture was that. Hats off to you Mr. Jeff Hanson
We need man like you keep it up
Thank you much sir, we are only given PDFs and our teacher does not discuss the lessons. You sir are our greatest help.
Extremely genius explanation fr
WOW...GREAT video. You're such a GREAT teacher. And GREATLY appreciate you...
I really like the way he explains things and he is funny.
Dr. Hanson make also an integral calculus online course
I'm doing calc 2 right now too! Good luck to ya!!
again thank u mr henson. WIsh i had u as a teacher
best lectures hands down
Thank you from Lebanon 🇱🇧
Thank you Mr. Hanson this video genuinely helped me so much may peace be upon you.
Professor Hanson, thank you for excellent introduction to 3D Vectors.

Been lookinfor past 2hr to sth like this vid
Thanks Mr.pheeeeee😄
you beautiful beautiful bearded man. you saved my grade and i love you for it !
😂😂😂….. mine too
Your teaching style is so nice and funny
Sir, I hope I pass and hopefully its the exam and not the other way.
You literally taught me such a good method just a quick question for delta z what if the professor gave you a triangle instead of a angle
Thank you for the hard work! I salute your passion and dedication, I hope you inspire others to teach in such a remarkable way. Godbless Sir!
Thank you for this. I'm a senior electrical engineering student and statics might be the hardest class I take this semester lol
Wow. Im doing aerospace engineering and rn statics is easily the toughest class :/

@@jordanwillis243 its only the start of 2nd week, we had our first homework assignment and i got 2/10 correct
@@Error-br1uy Hey, that happens…. And it’s only one assignment. I’ve made 35’s on midterms and still passed the class. What was the homework assignment over? Moments and force equations?
@@jordanwillis243 Wow. And right now it’s just masses and forces in 2D/3D space. Calculating masses/stress on cables, pulleys, etc
What's great about those identities is that I just learned them from multivariable calculus. everthing is related
Love you boss, you made it so much easier.
You make this look simple huh!!!!!

I think that in the 2D the Fx coordinate is always cos as in the unit circle, and on the plane it’s Fx= Fcos(theta)
Thank you sir!! You're a great explainer❤
Kudos to you sir
This was very helpful, thank you so much :)
Thank you Sir ❤❤
You are awesome! This was so easy to understand, thank you!
I love your comment!
Waooo. Atleast now I understand something
Dude, awesome video !!!!
Thank you Prof
You are a god
Bahut achha lga sir
You are the best
I LOVE YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The blue triangle equations will be different if we are using a different orientation of the axis, but it’s still all the same.
thank you
What happens when axis changes? My professor likes switching the axis and I was wondering how it affects those equations?
I would also like to know this :)
I second that
Very interesting and funny guy. Liked your vidoes. :)
banger video
Hero.
sir -thank u for excellent lecture= pls solve example -amarjit =india
I need some extra instructions on how to find Qx/Qy for force F for a similar question, really stuck on it.
When the axis letters are switched how does this change the equations if at all?
Dr. Hanson I get what you are saying all day long. I do not understand the way the book explains it. Thank you
I love you
12:18 im trying this equation for a stupid statics problem that looks like a green metal thing stuck to piece of stone. For some reason... the Fy and Fx values are switched... sorry if im not making sense
thank youuuuuuuuuuuuuu
Love u❤️🤭
❤️❤️❤️
You seem to have reversed the roles of phi and theta as compared to how Hibbeler uses them. Is there a reason for that?
Sir can u give me example of 3 components of a vector in our real life.
2 D components we can understand
e. g. A box kept on inclined plane.
Weight can be resolve into 2 components.
Mg sin θ and mg cos θ
Why are the axis all reversed? Isnt y vertical, z 3d, and x the horizontal axis?
The axis is imaginary ..it can be anywhere
What is F subset h? Where did you derive it from? Thanks for your videos
I figured out whatF subset h stands for!! It is the hypotenuse of the imaginary door which will be the vector projected on the plane looking down from the helicopter to determine how far it swung from the X axis.
i have a question , Does the blue triangle equations work for all 3D problems ? i just substitute the variables i have identified
What statics book are you using?
7:50 very important people take notes here
Is there a proper term for these "Blue Triangle Equations"? I could've sworn I've seen these in my multivariable calculus textbook but don't remember what they were called.
I guess my name changed to Johnny and I'm now weak sauce 😵💫
What do I do when I dont know theta sub 2 though. Or F. I was only given Fx, Fz, and the angle between F and the Y axis :(
Whats thename of the textbook heused
DO YOU HAVE A VIDEO 7 IN THE SERIES IT SKIPPED FROM 6 TO 8
Yes definitely! Are you on the playlist?
Where does Fh come from? Can anyone explain it a little more in depth?
what book do you use?
Dude, what book did you use?
I'm just watching for fun! :(
Which book are you talking about?
I think Hibbler 14 edition
Sir which book are u using? I mean i want to know tha name of the book u showed at around 2.00
Looks like Hibbeler.
What's the book you just referenced?
Its Hibblers Statics book
