It's because its not quite right. It is a bit more complicated than that. He's not taking into account how these forces vary along the length of the beam. There are actual equations that involve the position (x) that generate the actual curves instead of arbitrary lines he drew.
@@armandmatossian2081 The equations are represented by the graphical method. Split the beam and do the analytical method and you will find the same results. At the end of the day, the relationship between sheer and moments is an integral so what he does here to skip doing the cut and check method of moment drawing is correct. The integral of a flat line is a triangle as the area increases linearly with distance. The integral of a slope is a curve etc. People should learn both methods as they are equally applicable.
*** THANK YOU* I was genuinely having fun learning this and it makes *SOOOO MUCH SENSE NOW!* Order of the lines? *GENIUS!* Ski slope analogy? *BRILLIANT!* I was rethinking choosing engineering not too long ago, but you've rekindled my love for it again. I'm out of the darkness and can once again see the beauty that is engineering. *Thank you,* Mr. Hanson. Really thank you.
Thanks, Jeff. I am a Civil Engineer working for 7 years and I learned a few things that I should have when I was in College. They never taught like this.
Dr. Hanson, You hands down have THE BEST explanations for me to grasp the concept. I've been coming back to your videos as I progress throughout my education. Thank you so much for taking time out of your busy schedule to assist students from all over the world. You have truly made an impact in more lives than you know, and we're so dang blessed to have amazing people like you helping to make successful engineers!
Sir your style of teaching is so interactive and effective,you're doing a good job unlike cold profs who only dictate the lesson like robots.Keep up the good work!
Thank you for explaining this so straight forward and simply. So many professors suffer from not being able to do that. You kept on the current subject and didn't speed up to fly through anything. You spent the time needed to fully explain and justify all steps you showed. Thank you again!
Doing refresher stuff for my PE in structural. Focusing on reinforced concrete (have been using programs that do this for me and other engineers, but know I will need to do these diagrams myself) and am absolutely loving this. Bam! Wooop! Love how you do that. Keeps it interesting and it is obvious you like doing it. Thanks a bunch for the refresher!
Thank you so much! I'm sharing this video with all of my classmates. With all of the remote learning happening right now, my professors are pretty unorganized and the lectures are unclear. I learned more in 19 minutes with you compared to hours that ive spent looking through the textbook and notes trying to figure out the missing pieces. Thanks again!
Cannot express how much this series has helped me out, the explanations you provide are magnitudes more comprehensive and understandable than my actual professor. Major thanks!!
this man is amazing. I was lost before I watched this and now I am very confident in my ability to do this. The way he described this concept is superior to anything else I have seen. Truly amazing.
This is my second time watching this video in a span of 4 years and this is so incredible. You are the best. We need professors like this gentleman in school.
For whatever reason I had so much trouble with this topic, this video helps SO much! Especially the order of lines and the slow to fast thing, those were some of the main points of confusion for me. Thank you!
It really helps when lecturers state the relationships, how to set up the solution diagram/s for the interaction of those relationships and then how to solve the problem/question. I’ll be adopting the three levelled diagram when calculating the shear-bending diagram. Thanks Jeff.
I really love when someone can master in his profession, no matter what that profession is, even it's something not seem so exciting like teaching a class. If you can explain thing like this you have my respect.
I have a professor that took two weeks to barely teach a class this stuff and I just come to you and learn it in twenty minutes better. Thanks professor
Thank u for pointing out where the forces going at each point. Putting yr finger at wt point then other finger showing what direction really helped me. Yr the only person Ive seen on youtube to do it this logical way 👍
I’ve just gotta say I’ve been watching your videos for two years now and the way you teach is extraordinary. I bet you’d make Richard Feynman himself proud. Thanks from Australia!
Bro, I was smiling the entire time because of how simple you made it to understand, like where have u been. I just wish I discovered ur videos earlier.
This is the best video series ever, I watch these videos before my lectures so I know what my professor is talking about. I truly appreciate these videos, thank you Jeff!
Just 5 days after my statics exam you publish this :(. Good thing i passed statics with a solid B thanks to your videos. Awesome teacher. Awesome channel.
My native language is spanish, I am listening your video meanwhile I am at work doing my tasks and I really can get every concept that you explain on the video, good job professor!
I enjoy these diagrams, but have struggled with some of the finer details since college. Now studying for my PE exam 6 years later - glad I found your videos. Thanks
Bravo sir! This is the most clear presentation I have seen on screwtoob. I had two college professors that taught statics and steel framing the way you do back in the early 90s.
thanks. I was struggling going over the explanations in "Form and Forces". This made it so easy to understand and I was even laughing out loud at our ski slope explanation. This was super helpful. So happy to have taken the time to watch through it.
woww i have been struggling these things for like days and just 3 minutes into your video am learning every concept..you such a wonderful lecture with a great personality i wish our lecture was like you.thank you
I was stressed out about being able to finish my mechanics MCQ paper on time but this method saved me and helped me to get an A+. Very thankful for your teaching sir!
Never stop teaching! You're excellent! (Why am I paying for a bored professor to teach me statics when I could literally watch you and learn so much more?)
Oh man! That was excellent! C student here…long time engineer with PE license. Been a long time! Great refresher, understand it better than I ever have!
amen to everyone's comments. if only all engineering profs were like Jeff Hanson. school would be easier and more fun. i hope this channel is helping him rake in the big bucks
Thank you, you are better than my teacher. I wasted an entire day trying to understand, and in minutes you were able to make me understand very well by the way i am non english speaker
Great lesson! One little detail: the parabolic decrease in M should not start horizontally but with a slight downward slope. The details can be found as follows: first pretend it's a linear shear force; this corresponds to the rectangle with area -16, which would get you from M = 28 to M = 28-16 = 12. Sketch that line to see the initial slope; use that as the starting point for the parabola.
You're literally a godsent , Prof. I really appreciate on how you make this course seems so simple and easy to understand. I can't put in words on how much you had helped me throughout my university. May God bless you , Prof.
This was an amazing video. Easy to understand and entertaining. Thought i watched like 5 min, but i had watched 15min. Usually its the oppsite. You are truly a great teacher
this man's explanations are clearer than clear water.
certified goat.
I was just about to say that; until I read your comment😂😂
@@dyota2277 😂😂😂 bro ur taking 242 rn?
these videos are remakes of older statics videos. he didnt need to remake but he did. what a goat
I was watching some videos on my native language and I understood them way less than this legend
I think so to you !
Just 7 minutes into the video and I just can’t help smiling and appreciating this man. Such a great teacher with likeable personality.
I read your comment at 7:20 with the same exact expression in mind hehe some teachers have a gift to teach, and others are just there to try...
The Order of the Lines is brilliant! No one explains it that simply.
exactly bro HAHA. All our professor's saying is to memorize things, not understand. Unlike the lessons of Prf. Jeff

Dude I have never felt love like this before you make it much understandeble than my books been struggling with this for a week

You are such an amazing professor, every teacher should learn from you
This man is such a phenomenal teacher. He explains things so well. Most professors couldn't explain the difference between an elephant and a rock.
Both grey and heavy ... 🤣
Best proffesor ever , i didn’t understand anything from 30hours at uni but understand anything in 19 minutes :)
i feel so lucky that these videos exist while i am learning civil engineering. thanks so much, jeff.
Thanks, Jeff. I am a Civil Engineer working for 7 years and I learned a few things that I should have when I was in College. They never taught like this.
Mine they caught me a formula v(x) and m(x)

Hey man, you're the reason I'm passing statics this semester. thank you for all your videos!
Finally I found the correct channel. Thanks for sharing that valuable information. Greetings from Peru.
I was trying to revisit (relearn) my student days over 40 years ago and I find Dr Hanson's teaching superb.
Cannot express how much this series has helped me out, the explanations you provide are magnitudes more comprehensive and understandable than my actual professor. Major thanks!!
this man is amazing. I was lost before I watched this and now I am very confident in my ability to do this. The way he described this concept is superior to anything else I have seen. Truly amazing.
ive been struggling on these for the past week and this video made it click instantly. thank you so much!

Prof Hanson, I have no doubt that your purpose on earth is to impart knowledge. One can't ask for more explanation. Thank you!
Watched it again a year later for my FE exam. Thank you so much! this is so far the best FE/PE exam video I've ever watched.
Bro, I was smiling the entire time because of how simple you made it to understand, like where have u been. I just wish I discovered ur videos earlier.
Thanks for the video. You've really helped me understand Shear/Moments diagrams more now.
Jeff Hanson for President 🤝
This is the best video series ever, I watch these videos before my lectures so I know what my professor is talking about. I truly appreciate these videos, thank you Jeff!
Dr. Hanson thank you so much! I will be watching all your series from now on!
Just 5 days after my statics exam you publish this :(. Good thing i passed statics with a solid B thanks to your videos. Awesome teacher. Awesome channel.
1 million views and you deserve it!
Dr. Hanson, you make these courses so much fun!🤗 You are much appreciated across the globe. Thank you so much🙏
My native language is spanish, I am listening your video meanwhile I am at work doing my tasks and I really can get every concept that you explain on the video, good job professor!
None of my professors have ever explained anything this clear. Thank you 🙏
I wish I have instructors like him in my uni ... he makes everything fun and clear to understand!
Thank you so much Dr. 19 min and clarified every single thing
This man saves me before every test and exam! He explains it amazingly!
This video helped me so much! I have had three professors teach me this concept, and I finally learned it in this video. You did an amazing job!
I enjoy these diagrams, but have struggled with some of the finer details since college. Now studying for my PE exam 6 years later - glad I found your videos. Thanks
Bravo sir! This is the most clear presentation I have seen on screwtoob. I had two college professors that taught statics and steel framing the way you do back in the early 90s.
This 20min vids is so Helpful. It makes so easy than understanding a book for about a day...
thanks. I was struggling going over the explanations in "Form and Forces". This made it so easy to understand and I was even laughing out loud at our ski slope explanation. This was super helpful. So happy to have taken the time to watch through it.
I can't thank you enough i wouldn't have done great in the course without your videos.
woww i have been struggling these things for like days and just 3 minutes into your video am learning every concept..you such a wonderful lecture with a great personality i wish our lecture was like you.thank you
The man who made me love statics. Big respects.
This is brilliant. Thank you so much for sharing and actually making statics stick in my brain.
he is one of the coolest tutors , I have ever seen on youtube. Great explanation
If we had more Jeff Hanson, there would never be shortage of engineers in this country. Thank you Dr. Professor
Im an engineer, and your explanation helped me to understand better this approach in a simpler way. Appreciate it Jeff!! Im subscribing.
I was stressed out about being able to finish my mechanics MCQ paper on time but this method saved me and helped me to get an A+. Very thankful for your teaching sir!
I was only taught the equation method where you get the equation then plot points. Thank you for a very fun an easy to follow explanation of this.
liked the video immediately he sung,,,,,,,,,thank you sir jeff
My strength of material teacher spent 2 mins explaining this and moved on like everyone understood it or smthn...ur the best ❤
Jump by Van Halen, what a classic. I'm 20 but I love the 80's glad this professor has a good taste of music. Caught that reference! 11:13
Thank you Jeff, I came to this video for mechanics of materials and am now back again for structual analysis
Truly THE goat
ive actually found the jackpot with these lessons. thank you
Sir you are an absolute legend, I've watched a few videos on this topic but couldn't understand them. You explain it so well. Thank you.
this man is GOAT at his craft. am loving this!!!
Never stop teaching! You're excellent! (Why am I paying for a bored professor to teach me statics when I could literally watch you and learn so much more?)
hope every teacher is as good as you teach ! im enjoying the sound effects and the singing haha learning is fun
omg!!! you are a perfect teacher.thanks from Turkey
I have never enjoyed Statics class like this before. Thank you very much sir!
best teacher that explain that problem
Oh man! That was excellent! C student here…long time engineer with PE license. Been a long time! Great refresher, understand it better than I ever have!
This helped me a lot to prepare for my midterm exam. Thank you!
It is impossible to ask for a better explanation than this!
Cracked me up with computer noises during the calculation. The best teacher I have SEEN IN YEARS!
first guy on Earth who makes learning fun .....Thank You Sir!
You are an amazing teacher. Keep up the good work.
amen to everyone's comments. if only all engineering profs were like Jeff Hanson. school would be easier and more fun. i hope this channel is helping him rake in the big bucks
Thank you, you are better than my teacher. I wasted an entire day trying to understand, and in minutes you were able to make me understand very well by the way i am non english speaker
You can use rule of umbrella when choosing parabolic line
you are a life saver Dr.Hanson
well done, you are so useful thank you
i love how you explain things and make them sound easier to think of
The wonderful Mr Jeff Hanson, saving GPAs since 2021 👏
Eng Jeff u will always be remembered for this wonderful explanation much love
I love this man. I can't help but to laugh at all his silly, but hilarious, comments. Thanks a lot professor ❤
I cant thank you enough. You made me understand something so fast that my lecturers couldn’t teach me in months…

you are the best teacher in the world, every word you explain is etching on my mind involuntarily, thank yooou
The easiest explanation on which parabolic line to choose. This helped me a lot! Thank you so much!!!
You're literally a godsent , Prof. I really appreciate on how you make this course seems so simple and easy to understand. I can't put in words on how much you had helped me throughout my university. May God bless you , Prof.
Incredibly simple way to explain this.. thank you!
This video was amusing, thanks Dr. Jeff you're genuinly an amazing person.
thanks for singlehandedly getting me through my statics class I had to take online thanks to covid. I got a A-. You're a real one.
no other videos could make me understand this material this quick
Such a great video explained perfectly in 20 minutes what i couldnt master after half a month of statics
This was an amazing video. Easy to understand and entertaining. Thought i watched like 5 min, but i had watched 15min. Usually its the oppsite. You are truly a great teacher
out of everything i ve watched youre the only helpful one thank u
jeff you are the GOAT of all time ever
NO TO SKIP ADS TO THIS MAN BECAUSE HE DESERVE IT PERIOD
You are a special teacher 🙏🏽God bless you!
