| 41. | Once this technique has been mastered, the rotation speed can be gradually increased until the balls separate in the hand.
|
| 42. | In fact, theories of disk galaxy formation are not successful at producing the rotation speed and size of disk galaxies.
|
| 43. | Strobe light measurements can be inaccurate because the light may be flashing 2 or 3 times faster than shaft rotation speed.
|
| 44. | By controlling the rotation speed of the disks, only particles with a certain known velocity could pass through and be detected.
|
| 45. | One concern was whether at these high speeds the alternator might disintegrate due to the high rotation speed tearing it apart.
|
| 46. | Powered rotation also allows the ladle to have a number of rotation speeds which may be beneficial to the overall casting process.
|
| 47. | High rotation speed provides high centrifugal force that allows the suspended solid in feed to settle on the inner surface of basket.
|
| 48. | The rotation speed problem comes into effect when the differential gearing is a high ratio and an overdrive is used to compensate.
|
| 49. | The centrifugal force on the spinning blades increases as the square of the rotation speed, which makes this structure sensitive to overspeed.
|
| 50. | Another improvement has been in the quality of drive motors and power supplies, which can now maintain almost perfect constancy of rotation speed.
