Drawing Shear and Moment Diagrams for Beam

This is an example problem that will show you how to graphically draw a shear and moment diagram for a beam. In general the process goes like this:
1) Calculate support reactions
2) Draw vertical lines at discontinuities
3) Draw graphically by applying relationships for loading, shear, and moment
dV/dx = w (slope of the shear diagram is the value of distributed load)
dM/dx = V (slope of the moment diagram is the value of the shear)
change in shear = area under the distributed load
change in moment = area under the shear diagram

Four years back i was a student and your videos help me a lot, today i'm an engineer, so thanks for share your knowledge with us.

Greetings from Brazil.

I am a mechanical engineering student in my final semester, and your videos have been extremely helpful for me in the last 2.5 years. I am extremely thankful to you for making such amazing videos, and I love how cool your teaching method is. Just so fun to learn from you.

When I graduate this semester, I will be keeping you and your videos in mind. Thanks a lot for all your help! ♥️

I am an architect and civil engineer graduated from the University of Malta two years ago. Thank you for your videos, they are an easy-going revision for me which I enjoy watching and working with you 👌

You saved me for Structural Analysis! Class is over but I am still going to watch all of your new videos because they are so good.

[dylanbolton]

Literally cannot describe how useful all of your vids are and your great humor always keeps my interest. Thank you and please continue making these gems my man. Appreciate you more than you know!

[AlanaClaassen]

So well explained, thank you so much for sharing your knowledge on this topic so thoroughly and clearly!

[michaelkrueger]

You are a great teacher! Thank you for making this video!

[mark-qidi]

Your video was embedded on our learning page, and so I had to come look for your channel. Really dig your energy! Greetings from South Africa

good exercise. sometimes i have to do beams like that to keep it in my mind after exams. thanks dude

@Structurefree, can u please show me the derivation of how you know whether concentrated moment will cause the graph to jump up or down in the moment diagram?

[sbduman]

Wish I could discover you way earlier!

[Peepepops]

Love the explainations. Really helpful during this time of online classes.👍🏻

The addition of the moment in the equilibrium equation, , , does it matter if it is pointed counterclockwise

[StringTheoryMx]

You are awesome bro, thanks for this amazing content!.

[EngahmedHussein]

Nice ❤
Can you tell me how you do this type of videos .. Thanks Alot
I need to make videos like this to my students

[usernumbereighteen]

Hey man, great video. How would I know when to use the other parabolic moment curve. because to me it still looks like it has a positive slope. Unless there's something I'm still not getting

[ntonyjaime_]

How do you calculate the maximum shear force and maximum bending moment?

[joshlamanna]

it would be great if these were not interrupted by ads every minute

[mrfox]

the shape of momen diagram should be the same of the shape of deformation of beam. It will be easier to imagine
