| Nov 12, 2014 at 3:11 | comment | added | user65081 | I am not sure to understand which torque on the blue axis is cancelled by which torque on the disk. Can you give me a specific pair (such as torque from F1 cancels torque from F2, or whatever you think is the case)? | |
| Nov 11, 2014 at 19:39 | comment | added | Sx7 | I added information, imagine 2 red disks only at bottom (no others gears), there is torque on blue axis, torque on disk and heating. But with all gears with mass, each time I draw forces, a torque on blue axis is cancel by a torque on a disk. It's like with 2 disks there is more energy from heating. | |
