Measuring the Moment of Inertia of Rigid Body The moment of inertia is an important physical quantity in the mechanics of rigid body and basic concept of physics.The law of rotation is the also the basic law of physics.The measurement of moment of inertia is an important parameter for studying,designing and controlling the motion of rotating objects.Its value is related to the mass distribution of rigid body and the position of rotation axis.The moment of inertia of some rigid body with complicate shape is normally obtained from experiment.Measurement of the moment of inertia of rotating systems is also a common subject in real productive practice. Purpose: 1.Learning to use inertia experimental apparatus of rigid body 2.Studying the relationship between the external torque on rigid body and its moment of inertia;Measure the moments of inertia of regular objects and compare them with theoretical values 3.Studying the relationship of the moment of inertia of rigid body with its mass and mass distribution 3.Treating data by graphing method;Knowing and mastering its basic requirement 4.Proving the parallel axis theorem* Equipment: Inertia experimental apparatus of rigid body,weight,meter rule,stopwatch.
