You're the only reason I'm passing Statics. Definitely using your videos for Solids next semester!!!! you're truly a lifesaver.
"That's perfectly straight" LOL. Jeff has such a relaxed, fun way to teach. Puts a smile on your face while you learn.
Jeff Hanson is the Bob Ross of engineering, change my mind I dare you
there are no happy little mistakes in engineering.
This is coming in sooo useful for my aerospace engineering course, I struggle understanding "why" something is the way it is, so far you have been super clear with everything
Jeff, you are the freaking man!!!!! I love how simply you taught this. I really appreciate how you mentioned calculating the area from the shear diagram, it helps tremendously in calculating the Max Bending Moment!
I was terrified for my statics final and after watching your videos I’ve never felt more confident!
How'd it go?
man i am learning more in a 15-min video than in hours of lectures in my uni. thank you so much
Enthusiastic teaching partnered with clear explanation and tips, thank you sir!
Good thing I'm taking statins after June 2020, I don't know how people passed before your videos were a thing
took it summer of covid starting. It was horrible. His videos helped tremendously, but it was horrible.
@@gp7493 which uni r u from mate?
DR. Hanson, thank for another classic and awesome lecture of Shear Moment Diagram Problem with Moments. These lectures are very helpful to many students all across the world.
I often wondered why things are the way they are, until I found you. Thank you, Sir! ❤
I wish I could meet you and thank you in person! I used your videos in school during strength of materials, then helped prep for FE watching your lessons, and now I'm studying for my PE (Mech: MDM). I appreciate you!
What a wonderful way to teach. You truly are a saint Sir!!
Thanks a lot for your teaching. It's helping me a lot during my studying
You’re the best! I had difficulty with this but you made is easy for me. God bless you man
I got a trick for the fast and slow type of curve part sir. Just draw a circle, divide it into 4 regions, and then put "PD" on the upper left hand side (Positive area, Decreasing slope) and then "NI" on the upper right (Negative, Increasing), "ND" on the lower left, "PI" on lower right.
so taking that example at 12:49
since the area of the shear is Positive and then the slope is decreasing, then it would be "PD" and since PD is at upper left region of the circle the curve would steep then slow 😊😊
Thank you omg !!! I was having issues with visualization!!
if only I can send a picture 🤦
you're the GOAT
the mnemonic for this guys
is "Please Dont Neglect Infants
Neglect Dumb People Instead"
PD NI
ND PI
@@tutingrubena1584 I think this doesn't work when the distributed load is a triangle or does it?
Thank you soooo much for the help Dr. Hanson. I wouldn't of received my degree without it
Jeff, you're a LIVING LEGEND
i am out of words you are the BEST..............Thank you very much
Dr. Thank yoooouu soooo muuch, for the first time in my life, I understand this topic, thank you very much, may God reward you with heaven
tnq so much you are the only teacher that i have ever seen . very simply teach
This man is a legend ❤
Jeff... I love you man.... You are going to help me get this ME degree and I am so thankful.
sir im from sri lanka,
Im very thankful to you as i tried so much videos to get the clarification on bending moment diagram,but i did not receive full clarification,after watching your video i get the 100 percent clarification on Bending moment diagram.
thank you so much sir,and also like your coolness during lecture,we expect more support from you sir..
Firstly, greetings from trouble and sadness center of the world, IZTECH. I passed statics with your enthusiastic lesson expression.
yarın final var hangi hocadan almıştın
Your explanation of the parabolic curve using the trick of slow to fast contradicts each other. can you check this please and correct the anomaly? I am bit confused!
I'm doing my post graduation and these videos are amazing to polish your concepts
Here I am, seemingly for the millionth time, in my final semester of college, for a quick review. xD
I'm forever thankful for these videos.
You're appreciated. You're gold. Bless you.
Normal professors make it look easy. Jeff Hanson makes it feel easy.
Thank you, thank you so much!! You are unbelievably helpful
thanks a lot sir! , for making our subject much more easier than it use to be !!
Dr. Hanson, your videos are of great help.
Thank you.
I will never forget the John Denver moment! I wish my University Professors were so funny like him.
But in lecture 59 Shear diagram was slow to fast and you put the moment diagram the same as this ! Why?
Haha this is so much fun, I actually feel like studying again🌚
Great video, right to the point and explained it perfectly!
Thank you so much. Wayy better than my profeesior. Dude gets angry when asked to explain a step
You are an amazing teacher. Thank you Jeff
I have mastered this now. Thank you sir!
Muchas gracias, ha explicado todos los aspectos que me resultaban confusos durante los diferentes ejercicios.
I've watched so many of your videos and I just realized you sound like Dr. Phil 😄
Thank you so much for these videos!
hocam var ya You are LEGENDARY THANK YOUU I finally got it
you cant knock out your MA!!! 😂😂 TOS will never be the same to me again. GOATED tutor
i understand you better on 2 times speed than i do my professor when hes talking to me one on one. thank you
You made this so easy for me.Thanks a lot.
the kitchen concept got me😅👏👏👏👏👏👏
U are alot of fun sir😅I've never taken lessons while am smiling b4 🙂🙂 U make everything easy
thank you for this!
Sir u are such a great person. Thank you so much for these videos.
the moments on the smile don't follow the right hand rule though. i don't understand why the moment is positive when doing the equilibrium equations but negative when doing bending moments.
really helpful videos jeff thank you so much
You are awesome Dr. Hanson. 10Q so much ❤.
You just earned a subscriber... Keep up the good work man
6:56 is the most relatable moment in the history of engineering online lecture videos
I assumed downward force as negative. but I started the shear force diagram from the free end, and my graph falls below the X-AXIS. Is this right or would I be marked down? the shape and values are exactly the same as Jeffs'
I really appreciate this and you!
"That´s perfectly straight as you can see" 🤣😂😂
How did you get 12x6 for the triangle area? Wouldn't it have been 14 x 6 since it was 30 kips high and we subtract the 16 for the rectangle below? I appreciate any clarity
nope. rectangular shear width should be 18 brotha...
If TOMMOROW, in fact today, because is after 00 here, i manage to take a 5 (the minimum grade in romania to pass an exam) i will subscribe your channel and share it on the watsapp group and Facebook group and everything my Coleague has. THANKS FOR YOUR WORK!!!
Good teaching and very engaging, keep the good work up
So the sign convention for moments is the opposite of what it has been all along? That's not confusing or anything... :)
The sign convention for bending moments is different than the sign convention for moments in general. Jeff talks about the sign convention for bending moments in lesson 57.
Thank you
shouldn't be the Moment at A already be in terms of kips only? The ft. unit is cancelled by multiplying the load by 6ft
What happened to lesson 59 in the statics playlist ?
The only thing that is confusing and illogical is the use of kip when the standard is KN.
Thank you for this. You are a LEGEND!!!
i think there is a contradiction in fast and slow stuff in your previous video (lesson 59) and this video. i think curve should have been the other one in this video .
Thank you so much for these. I'd rather pay you than my university cause I learn nothing from them
According to lesson 59:
small to large change = convex
large to small change = concave
Why was it the opposite for this problem when drawing the M graph?
In the previous lesson, the slope started in the positve direction. But because it starts in negative it gets inversed I believe
These videos are excellent!
You are much better than my campus lectures
Thanks Jeff!
South Africans🇿🇦
I wish I found your videos earlier.
wish i could double like the video youre a great teacher
Man... U r amazing... Thanks a lot
thankyou for making it so easy
thank u
Thank you, very helpful
No idea why is Moment taken as negative if clockwise forces are positive along point of rotation
You are a GOD
This was a helpful video.. thanks
i love you
ew
Ew..
Thank you. This will help Shannie, joke, Also mee..
@aningmaster
Thank you so much sir!
Does the moment diagram have to return to zero?
Great Stuff! prefer metric - it seems easier....
absolute Legend
hello sir what whappwn if the 8kp force is not given
Thank you sir !
OMGGGGGGG YOU ARE THE BEST!!!!!!
thank you sir❤👍
GOAT!
In my final, I got a problem just like this one, but with a vertical force on the right end..
So it was impossible to do
We all did very bad..
I hope I pass this shit course🤦♂️
(The vertical force was an unknown)
Please where how did you get the 30 for the AY at the fixed place
0=Ay-12-10-8 then rearrange
Very helpful
Sharner question solving
he is just exelent and looks kinda like walter white hahah
