Shear and moment diagram in Mathcad

Hi

I have this beam that i have i shared in two sections. I have determined the equations for normal, shear and moment. Now I want to draw them in Mathcad but I don't understand how to do it. I have watched some videos in youtube but it didn't help so much.

I use Mathcad 15.

I really hope you can help me!

Thanks in advance!

Re: Shear and moment diagram in Mathcad

Your beam does not appear to be in static equilibrium; where are your constraints?

A simple example:

Re: Shear and moment diagram in Mathcad

Hi Fred,

Thanks for your answer!

There is only one support on my beam and that is placed at left side, Cx, Cy. From point C to FAB there is 600 mm, and the totale length of the beam is 1634,3 mm. At the end of hte right side there is a force F=1502,46 N

Was it what you mean with constraints or?

Thanks i advance!

Re: Shear and moment diagram in Mathcad

This is how I would approach it, assuming a cantilever beam at the left end:

Re: Shear and moment diagram in Mathcad

The most of the Work sheets/files are created with other programs, I only use Mathcad 15.. so can't open them.

Re: Shear and moment diagram in Mathcad

Hi so-3,

This is the short way to demonstrate plots in MC15.

Hope the attached File will help you for the first steps with plotting M(x) and FQ(X).

It's really easy to do for you.

Best regards, Volker

Volker
