Starting Torque Advice: 52.5 Kg m^2 at 230RPM

AI Thread Summary
The discussion focuses on determining the minimum starting torque required for a motor to rotate a 1200mm diameter cylinder with a moment of inertia of 52.5 Kg m^2 at 230 RPM. It raises questions about the relationship between the cylinder and the wheel, specifically whether they are directly attached or if they function like a gear system. The complexity of calculating the required torque increases depending on the configuration of the system. Participants highlight the need to consider both moments of inertia if the cylinder is attached to the wheel. Accurate calculations are essential for effective motor performance in this setup.

Hi Guys,
Could you advice on the minimum starting torque of the motor?

Moment of Inertia of the 1200mm dia cylinder is 52.5 Kg m^2
The cylinder is run by wheel that has 38mm diameter and runs at 230RMP

Thanks

Is the cylinder attached to the wheel? In that case, it's the two moments of inertia added together. If one is driving the other (i.e. the wheel-cylinder interaction is like a gear system), it gets a bit more complicated, and since it's been a while since I had to do a system dynamics problem, I can't give an exact answer.
 

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...
