AI Thread Summary
In Simulink, it is possible to model forces acting on a body directly using the equations of motion, such as in a spring-damped system, without necessarily converting to a state-space model through Laplace transforms. The discussion highlights that users can implement models based on the sum of forces directly. However, some may prefer the state-space approach for its systematic structure. Ultimately, the original poster confirmed that their specific problem has already been resolved. This indicates that both methods can be valid depending on the user's preference and the complexity of the system being modeled.

Hello everyone...


I have a little question on simulink. When forces acting on a certain body are given (just like a spring-damped system for example) can we automatically implement such a model in simulink by only using the equations of motion (mä = sum of given forces) or do I always need to convert the problem into a space state-modell using laplace transforms and determining the matrices…

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 '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...
