China Wholesale Hearing Threshold Factories – LMEC-5 Rotational Moment of Inertia Apparatus – Labor

Main experimental contents
1、Learn to measure the rotational inertia of an object with a trilinear pendulum.
2、Learn to measure the period of motion of the pendulum using the cumulative amplification method.
3、Verify the parallel axis theorem of rotational inertia.
4, the measurement of the center of mass and rotational inertia of regular and irregular objects (need to increase the center of mass experimental accessories)
Main technical parameters
