Regulation of angular impulse is an essential aspect of balance and fall recoveries.
The swing leg has also been shown to be important in generating the angular impulse required to neutralize the angular momentum of the body induced by the perturbation [17].
For example, during a forward trip, the backward-directed component of the GRF, acting on the tripping leg, passes posterior to the COM and contributes to the forward angular impulse about the COM (Figure 1).
(6) quantified how angular impulse about the vertical axis was generated during single and double pique turns.
In a spectacular accident in the late 1970s, the angular impulse caused by the destruction of a spinning epoxyglass composite rotor tore a spin pit from its attachment bolts and twisted it around in place, tearing away all the service lines including the vacuum pipe.
Properly designed spin test chambers include a separate internal burst-containment cylinder that is not attached to the chamber but is free to rotate under the angular impulse of burst fragments.
In a 3D motion analysis of the turn, they found that the dancers mainly controlled the rotational speed by swinging the free or gesturing leg laterally through torque exertion at the hip joint of the leg in clockwise and then counterclockwise directions, and that they supplied an angular impulse mainly to the gesturing leg during the swing when flexing the supporting leg and keeping their foot flat on the plate.
The following meanings of initial values have been chosen: for the amplitude of the AM envelope E([tau] = 0) = [10.sup.-3], for the envelopes' phase [THETA]([tau] = 0) = 0, for the radial impulses of the beams' particles [v.sub.j] ([tau] = 0) = 0 and for the angular impulses of the particles [u.sub.j](t = 0) [approximately equals] z[R.sub.j]([tau] = 0).
