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!

I can see I have calculated some thing wrongs.. the update is coming

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

A simple example:

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!

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

Fred thought the bearer was not in a static balance.
Your problem seems to be the plotting of the moments and the transverse forces, which has nothing to do with static equilibrium.
Of course, a carrier should be in static equilibrium.
Your carrier is not statically determined according to the sketch. There are missing bearings.

There are countless worksheets on the topic you are asking for. Try doing a search by writing in the box shown here, what you are looking for: search.jpg

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

Do research only in the mathcad worksheets:

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
