Two Degree of freedom Damped free vibration

AI Thread Summary
The discussion focuses on calculating the force and velocity in a two degree of freedom mechanical system with two masses, each supported by springs and dampers. The user has the necessary parameters, including spring constants, damping constants, and mass values, but is unsure how to apply them to find the desired outputs. The goal is to determine the forces and velocities in the dampers when the system is allowed to stroke 1 inch. Clarification on the specific calculations and expressions needed for this analysis is sought. Understanding the relationship between time, displacement, force, and velocity in this context is crucial for solving the problem.

I am trying to calculate the force and velocity of a primary and secondary suspension. I know the damping constant of the dampers and the spring constant of the springs. I see where an expression can be calculated where you input time and get x.

I'm sorry, I don't understand.

What exactly is your question?
 
I am trying to solve a two degree of freedom mechanical translational problem. The system has two masses and a spring and damper arrangement uder each mass. I was given the spring constant, damping constant, and mass. I want to dtemine the force and velocity into the damper if it is allowed to stroke 1 inch.
 
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...
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...
