Help with moment and shear force diagram

[ksk_10594232]

Hi 

I have issues trying to plot the Moment and Shear Force diagram of the following case. Any help is highly appreciated! 🙂

Maybe this will help:

It is written in German and contains a CD.

Here is a worksheet that can help you.

Thank you, but I don't want to derive the moment and the shear force diagram since I already know the functions. I want help with the plot.

Then attach your Prime worksheet with a clear description of your problem, and state which version of Prime you are using.

success!

I have managed to plot the shear force diagram but still need help with the moment diagram. 

I am using Prime version 7.0. 

File attached. Thanks for any help.

Something like this?

Can't explain the strange effect for x > 9,52 m. Changing the value of the system variable TOL to get a more precise numerical integration did not help.

Here is a clumsy workaround which should not be necessary

Don't have P7 installed, attached worksheet is in P9 format

Here is a simpler workaround which does not modify your definition of V(x).

Actually you don't have to split the integral at x=L/2. Any position lower than x=9.52m would work OK.

Thank you! 😀 That was exactly what I was looking for!
