The measurement system based on torsion pendulum is presented to measure the moment of inertia considering the effect of air damping. With the introduction of air-hovered turntable, the influence of friction force is reduced. In order to increase the effect of the air damping, damping paddles ...
Moment of Inertia refers to the property of an object in angular motion that is analogous to mass in translational motion. It is calculated as the sum of the moments of inertia of the mass elements in the body, where each element of mass is located at a different distance from the center...
Experiments can be used to determine the moment of inertia of a body with a mathematically unintelligible shape. The popular way efficiently uses the link between the time of oscillation of a torsion pendulum and the inertia moment of the hanging mass. Conclusion The formulas for the calculating ...
A measurement model based on torsion pendulum was established, in which nonlinear damping and nonlinear restoring force were considered. The calculation method of the moment of inertia was based on Hilbert transform. The motion of torsion pendulum showed the time-frequency characteristics due to the ...
