Consider the rotor of a gyroscope. The rotor is attached to a frame that is rotating about a fixed vertical axes with a constant rate of ω 1, and with the rotor rotating relative to that frame at a ...

Abstract: An instrument is described for the measurement of angular velocity and angular acceleration of a rotating shaft, based upon an optical angular transducer and an associated operational ...

Abstract: Aiming at quadrotor aggressive flight control, this article proposes an angular acceleration control framework based on incremental nonlinear dynamic inversion (INDI). A theoretical Lyapunov ...

The University of Virginia is investigating the use of a magnetohydrodynamic (MHD) angular rate sensor to measure head angular acceleration in impact testing. Output from the sensor, which measures ...

Frontal and temporal lobe contusions that were caused by a single sagittal plane angular acceleration impulse were analyzed. At neuropathological exam the depth, extent, and location of contusions ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Cognitive deficits observed in professional soccer players may be related to heading of a soccer ball. To assess the severity of a single instance of heading a soccer ball, this study experimentally ...

Ask any engineer what the velocity of a point on a rigid body is, and they will correctly say that it's the time rate of change of a linear position vector. Ask any engineer what angular velocity is, ...
