Writing shear and moment equations for a simple beam problem?

AI Thread Summary
The discussion focuses on writing shear and moment equations for a simple beam problem using Mathcad. The user is generating a spreadsheet for this purpose but is struggling with the integrals involved. It is noted that shear and moment diagrams appear correct, raising questions about the user's concerns. The advice given emphasizes the need for piece-wise equations rather than a single expression applicable throughout. The user seeks guidance specifically on setting up these equations in Mathcad.

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.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
