A torsional natural frequency of a mechanical system is a frequency at which the inertia and stiffness torques are completely in balance (see App. C). In the absence of damping in the system, forcing ...

Following calculation of the transient torque responses in the machine shafts, it is often necessary to estimate the amount of fatigue life expenditure in the shafts (if any) as a result of the ...

Little is known on the rotational torque that players experience on these fields. High rotational torques between the shoe outsole and the sports surface has been correlated with torsional injuries of ...
