AI Thread Summary
To determine the shear-force and bending-moment equations for the beam, the user has identified the loads and reactions, with W = 180 N, Ay = 60 N, and By = 1120 N. The discussion emphasizes the importance of understanding that simple supports can transmit forces but not moments. The user seeks assistance specifically with formulating the equations, indicating they have not yet documented their attempts. Clarification on the specific difficulties faced in deriving these equations is requested. The focus remains on establishing the equations necessary for further analysis of the beam's behavior.

Determine the shear-force and bending-moment equations for the beam. Then sketch the
diagrams using the aforementioned equations if necessary to ascertain key points in the
diagrams, such as the position between the supports where V=0. What is the bending
moment there?

The following is the figure and how I drew the Free Body Diagram. Remember, I only neglected the Coupled-Forces, not the m0ment they cause.

I found:
W = 180 N
Ay = 60 N
By = 1120 N

No need for the sketching part, I can do that. Just need help with the equations.

Any help is greatly appreciated.

By their nature, simple supports can transmit forces but are incapable of transmitting any moments.

What specific problems are you having with the equations?
 


I am having difficulty finding ".. the shear-force and bending-moment equations for the beam. "
 


What have you tried? Have you started to write anything down?
 

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...
