A motor rotates the driving gear in a mechanism used to turn a museum exhibit. The driving gear and driven gear have interlocking teeth. The force between the teeth is the same on both gears.
| Quantity | Value |
|---|---|
| Force between the teeth | 120 N |
| Radius of the driving gear | 0.030 m |
| Radius of the driven gear | 0.130 m |
| Minimum required output moment | 15.0 Nm |
| Minimum ratio of output moment to input moment | 4.0 |
Calculate the moment on each gear. Evaluate whether the gear system meets both operating requirements. Show your calculations.
