When you look up at the video because he stopped talking, then he sneezed and scares you! lol bless you!
And I just got to that part 😂
I'm about to take my last mechanics related final in exactly 2 hours. In 6 months I will finally have my Mechanical Engineering degree. I credit this man for a lot of my success with the traditional mechanics sequence course that uses the Hibbeler textbook. A few times for machine design classes I even went back to his lectures to double check my understanding of things. I thought it only fitting to go here first when I wanted to refresh a few skills I haven't messed with in a while just in case it shows up on my final today.
glad you made it!
hope u got it
@@gokublack9080 I did indeed.
awesome!! I'm taking my strength of materials final tomorrow and this guy literally makes finding the centroids of composite shapes easy!! "still struggle with it"
3:20, the start of COVID in america
😂
lol
3:15 Man! that woke me up while studying at 1:30 PM... Thanks!
Bless you
I was listening to the video through my home theatre system. I think the whole town heard his sneeze🤣🤣. Apart from that good lecture.👍👍
that sneeze caught me off guard not gonna lie. Fantastic teaching though, thank you so much!
Sir, I can't thank you enough for your videos. You are an amazing lecturer and I would not be passing my statics class without you and I'm sure other student would agree. You are truly an amazing person for changing so many lives. Thank you!
Thank you so much for the clear and life saving explanation haha. I am feeling like I have a chance at this test after watching and re-doing your examples by hand. Thank you a million!
Thank you so much DrHanson!
It's so refreshing watching a lecture by a teacher who cares about people understanding and likes his job.
You are a breath of fresh air.
bless you and this is great, I have been watching your videos all day, thank you.
Interesting. I kind of wish my teacher made it clear we could put centroids on empty spaces and consider subtracting its area from the overall area.
Professor Hanson, thank for another beautiful lecture on Centroid Using composite Shapes, Center of Area. I really enjoyed solving these problems in Statics.
That was a mighty sneeze. Bless you
Hats off to you I was cosidering skipping centroids entirely before writing my trial now I definitely won't
Amazing tutorial, made it super easy. Great job, thanks!
3:14 After I stopped laughing from Jeff sneezing I started to sneeze myself, not even joking 😂
Gosh i love you for this! Thank you ❤️🙏🏽
bless you for that sneeze and for the lesson
I love your teaching so much!!!!!!
You just made my degree a whole lot easier. Thank you so much!!!!!!
I increased the volume to max because I couldn't hear clearly. Guess what I heard clearly, the sneeze at max volume 😂, I nearly woke my roomies.
Thanks professor though. Your explanation will go a long way
Thank you Dr. Hanson.
Does any one one has any thoughts on why after I tried it the other way subtracting the triangle from the rectangle and my answers where close but not the same?
This helped, I understand it, and I started using negatives for empty areas and it scared me, but you reinforced my thought that it was true and that you do use negatives for totaling with empty shapes
Jeff Hanson? More like Jeff Handsome! Keep of the great work! I'm loving these videos, super helpful
as a NUST student from Namibia im not going to lie mr hanson has helped alot thru out statics and make sure u also follow his teachings if u r from there:)
You the reason I’m going to pass my statics final...Bless 🙏🏾
same lol
facts
studying for the final now, in 3 days! lol
All the way from Nigeria, sir, this has helped me a lot. Thank you so much, sir.
Bless you!
Your truly saving me
holy moly that sneeze was insaaaaaaaneeeeeeeee!!!!!!!!
Idk why this table system never came up in class. This is brilliant
method of finding centroids of composite shapes, really good
He sneezes 😂😂😂I love you. You're amazing
omg, I am back, and I passed my test with a 100% score thanks to you. Thank you.
2:50 for triangle, isnt the x-bar base/2 and the y-bar is 1 third of h?
ok, this was easy to understand, thanks
Bless you :)
Didn't know centroid is so easy like this😂
Thanks Sir Jeff!
omg I was on the Calculator wearing my headphones thx doc Lol ):
and bless u (:
3:20 Bless you!
Thank you
thanks for the sneeze, it helped me to focus at 2 AM 🤣
Thank you sir ❤️
bless you :D
Jeff, you're amazing and I love you dearly. HOWEVER, could you please fix the fact that your intro volume is 5x louder than the rest of the video hahahahaha it blows my eardrums out every time
bless you.
What if the rectangle and triangle was different densities
I had my speaker turned up and was looking at my paper. Almost crapped myself when he sneezed hahahaha
Bless you 😅
Hey jeff, fun fact my community college statics teacher cant find the time to teach us, since teaching remotely from halfway across the country in a nice warm state is so hard. She now has only posted 22 slides and a few of YOUR videos for the entirety of our curriculum for chapters 9 and 10 out of the pearson Engineering Mechanics : Statics book 14e. Do you allow this, should I reach out to my school about this?
I like table method!!!
bless you
The sneezing LOL
How the area became negetive for circle?
My third day of centroid these centroid sucked my blood I am at problem 50 in book
Physicist stepped on Mars but they couldn't find easy way to find centroid every problem have different formula and I am weak in derivative differentiation graph geometry shapes thier area volume
But still positive for every solution I watch 4 to 5 may be more videos then try to solve
You done great job you are legend its because of you I am at ch 9 had no Problem previous chapter and also this chapter you explain brilliantly it's me Don't have basic knowledge of before chapter 9 but I will overcome
Super
😂 the sneeze though
thank you, just.... thank you.
Why is the area of the circle negative?
Because there is a hole in the part. The area isn’t there, therefore we need to subtract it away.
3:30 , bless you!
why mister is the X in a rectangle is 0.35 ?
ASHHHHH SHOOOOW!
teacher why you don't came University of Gondar
3:19 Bless you! 🤧
3:20 it scared me lol😂😅
why is the .6 and .7 getting halved at the start?
the centroid of the rectangle is located at intersection of half it's base and half it's length.
Goated
am confused by y bar on second shape can anyone explain
Have you gotten the answer
3:17 bless you
Woow 100%
3:18
The x bar is not one third of the base it’s 2 third of the base
thats what i did too
It's 2/3 of the base if you were to do it from the low side, so basically the same thing. He did it from the high side of the triangle and that's why he used the 1/3. Don't forget that 2/3 + 1/3 = 1
O_O Bless you ☔ 3:16
the sneezee though
👍🏻
Mr Jeff
3:25 God bless you.
4:50 why is area negative???
Because we subtract that region from the main region. It is not there, we assume it is there, and because of that, we have to put a minus in front of it to show that it is not a "real region".
Sir i'm not able to understand the negative sign taken for area of circle
The circle is missing from the shape, it's an empty space. So you negative those empty spaces for the area
Ok sir
4:36 why the area should be negative
because the area will not be included in. The circle is a hole
god
u scared the shit out of me on 3;20
Time 8:42 lmao thank you
Didn’t try to cover that sneeze
Why are using points before the numbers, it is little annoying
🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤠🤠🤠🤠
I understood everything in statics but tell me why tf did this section give me a hard time
R.I.P to earphone users
بس اني عراقي هنا😂
You could’ve cut the part where you sneezed pal not really professional
From the bottom of my heart, thank you
bless you 2:55
3:17 lmao🤣
Bless you
