WebThe air friction damping is created in an air chamber by moving the piston in and out. As the piston enters the chamber, compression is caused inside the chamber. As the piston moves out of the chamber, a force is experienced by it. Air friction damping is the best suitable method of damping torque where the electric field is relatively weak. WebOct 31, 2024 · Obviously the damping constants for real lines are much larger than this. For real lines, the classical damping constant \(\gamma\) has to be replaced with the quantum mechanical damping constant \(\Gamma\). At present I am describing in only a very qualitative way the quantum mechanical treatment of the damping constant. …
