| 31. | In traditional systems, a stabilizing gyroscope with a vertical spin axis corrects for deck tilt, and stabilizes the optical sights and radar antenna.
|
| 32. | Like linear momentum, angular momentum is vector quantity, and its conservation implies that the direction of the spin axis tends to remain unchanged.
|
| 33. | Finally, during the last stages of planet building, a stochastic process of protoplanetary accretion can randomly alter the spin axis of the planet.
|
| 34. | A spinning wheel is mounted in a gimbal frame whose axis of rotation ( the precession axis ) is perpendicular to the spin axis.
|
| 35. | The lower gyro has its spin axis oriented along the east-west grid axis and is sensitive to torques about the north-south and vertical axes.
|
| 36. | Shock waves in the jets, which would emerge along the spin axis of the black hole, would accelerate certain particles to still higher energies.
|
| 37. | The satellite was spin stabilized at 50 rpm, but the optical instrument's data was poor because of an unsatisfactory orientation of the spin axis.
|
| 38. | An electron may be in a superposition of spin up and spin down, which corresponds to the spin axis pointing in some other direction.
|
| 39. | It was based on the same design as one used on IRAS and was able to vent helium along the spin axis near the communication arrays.
|
| 40. | Her angular momentum is her rate of spin multiplied by her moment of inertia, which depends on how her mass is distributed around her spin axis.
