investigation of mass moments of inertia in rotating, rigid bodies

Description:

• The resistance with which a rigid body opposes a change to its rotation is indicated by the mass moment of inertia.
• Here, the behaviour of the body depends on its mass and the distribution of this mass relative to the axis of rotation.
• Mathematically, the quotient of the rotary moment and the angular acceleration is the mass moment of inertia.
• The TM 610unit can be used to study mass moments of inertia of rotating bodies (hollow cylinder or solid cylinder).
• The experimental unit is clamped to a table-top plate via two support rods.
• A support rod supports the rotary axis with the studied body.
• The rotary axis is accelerated by a weight, pulley and cable with a drum.
• This results in a uniformly accelerated rotational motion.
• Using the measured time, mass and acceleration distance, we can calculate the mass moment of inertia.
• Systems with different masses and mass distributions can be studied in various geometries.
• Using a rotating bar with masses, it is possible to study the mass moment of inertia as a function of the radius.
