Writing shear and moment equations for a simple beam problem?

[rtrux4]

I am trying to write shear and moment equations in mathcad for a simple beam problem. Any help would be greatly appreciated.

Thanks

Im generating a spreadsheet in mathcad to do simple beam problems. Having trouble doing the integrals.

You shear and moment diagrams look OK, so it is not obvious that there is a problem. Why do you think that there is one?

I am trying to write out the shear and moment equations for the beam in mathcad. The attached figure was from Beampro (an analysis software).

You are going to have to write them piece-wise. Don't expect to find a single expression valid everywhere.

I know ill have to piece-wise them, but any idea how to set up the eqns in mathcad? The integrals.
