The concept of steady state

  • #1
Steady state is defined as the state at which at the temperature attained becomes constant. To say, there is no decrease or increase in temperature. It can also be defined as the state where the heat generated is equal to the heat dissipated. I have been capturing thermal images of a bearing in operation and see that the bearing never reaches steady state. I run the bearing on a test rig in a lab. So, the test rig is not a closed one. Can anybody explain whether the concept of steady state is achieved in actual ? Also, at the molecular level, can it be inferred at the steady state that the molecules are also in steady state?

There is no indication of how the bearing temperature was varying with time during this test. Maybe the OP just didn't wait long enough. One can only speculate.
