Effects of the racket polar moment of inertia on dominant upper limb joint moments during tennis serve. [PDF]

open access: yesPLoS ONE, 2014
This study examined the effect of the polar moment of inertia of a tennis racket on upper limb loading in the serve. Eight amateur competition tennis players performed two sets of 10 serves using two rackets identical in mass, position of center of mass ...

Moment of Inertia and Dynamical Symmetry

open access: yesSymmetry, 2023
We investigate how the moment of inertia of the atomic nucleus can be calculated in terms of the invariant operator of its SU(3) symmetry. This question is important for model Hamiltonians containing the moment of inertia explicitly, e.g., those with multichannel dynamical symmetry, which describes many different bands in a unified way.

Design and Analysis of a Moment of Inertia Adjustment Device

open access: yesMachines
The vibration frequency characteristics of a rotor system are directly related to its moment of inertia. In this paper, a moment of inertia adjustment device is proposed to adjust the frequency characteristics of a rotor system and better reduce ...

Moments of inertia by summation [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2023
This study delves into moment of inertia in rigid body mechanics, a crucial concept in physics. While it’s traditionally taught through integration, we propose an alternative method using discrete mass segments.

A Novel Moment of Inertia Identification Strategy for Permanent Magnet Motor System Based on Integral Chain Differentiator and Kalman Filter

open access: yesEnergies, 2020
In a motor control system, the parameters tuning of speed and position controller depend on the value of the moment of inertia. A new moment of inertia identification scheme for permanent magnet motor system was proposed in this paper.
