Shear and Moment Diagrams with Uniform Distributed Load

In this example, we calculate the shear and moment diagram for a beam under a uniform distributed load (F=-1.5 N/m). We can see that the shear diagram is the integral of the uniform distributed load (V=-1.5x+6 N), and the moment diagram is the integral of the shear diagram (M=-1.5 x^2/2+6x N*m).
For more complicated loadings, see this follow up video: • Shear and Moment Diagr...

Great video....the explanation was better than most videos that I went through..

[@Schlog1]

Great video, but there's a small error.
At 5:10 when you rewrite an equation to isolate M at cut C, you fail to change the sign of the term -6x when you move it to the RHS of the equation.
You correct it later when you define the M at a cut C as the integral of V, but the error is still there at 6:31 when you write the correct version.
They're both on screen at the same time. It's cute, but it's wrong.

I really like the depth of the analysis in the screencast, but can you go over more complex examples?

[@mrsoltys]

Sure. Do you have anything in mind?

[@asimmessi876]

Your perfect! Thank you soo much .

[@Frank_The_Tank22]

Excellent video, thanks for your time. Can you do one with a load that isn't uniform?

[@DrSoltysScreencasts]

Sure, What kind of loading do you have in Mind?

[@Frank_The_Tank22]

Dr Soltys Screencasts maybe with a couple of different forces at different points, as well as a distributed load with a positive slope w(x)? (I mean looks like a triangle load)

[@DrSoltysScreencasts]

Here's a video with combined loading

Thank you so much :)

thanks

Sorry, may I ask some questions? In 5:21, should it be Mc= -(1.5x^2)/2+6x?
Also, i want to ask that why we don't calculate the moment by using shear force?
I think shear force=resultant force(6-1.5x) and we can use it to calculate same answer
If we use shear force to calculate the bending moment, the (Mc) should be equal to 6x-1.5x^2
I know Mc= -(1.5x^2)/2+6x is correct answer, but why these two answer is not equal?

[@yl3485]

I just study this subject so i am confusing to above questions.

[@yl3485]

Oh, i got it. If we use shear force to calculate bending moment, it should be (6-1.5x)x+1.5x^2/2=6x-(1.5x^2/2), right?

Makes no sense. Thanks
