41. The same equations for the angular speed can be obtained reasoning over a rotating rigid body . 42. For a moment, consider the coins not as idealized rigid bodies but as real elastic objects. 43. In order for the cable to remain rigid body this restraint must be there ! !! 44. The non-orthogonal rotating coordinate system may be imagined to be rigidly attached to a rigid body . 45. The pole polar relationship is used to define the center of percussion of a planar rigid body . 46. Explorer 1 changed rigid body dynamics after nearly 200 yearsto address this kind of momentum-preserving energy dissipation. 47. Traditionally the Newton Euler equations is the grouping together of moments ) acting on the rigid body . 48. The resulting mismatch between body segments and tergites ) is the cause for this centipede's rigid body . 49. For 1998, the Corolla and Prizm use a new, more rigid body structure to provide better crash protection. 50. The Sonata's new, more-rigid body lends itself to reasonably responsive handling while delivering a smooth, quiet, comfortable ride.
