Rotational inertia Moments of inertia of different mass arrangements and bodies Features - investigation of mass moments of inertia in rotating, rigid bodies Learning objectives/experiments - investigation of the inertia of rigid bodies in rotational motion - determine mass moments of inertia of different, regularly shaped bodies - investigation of the mass moment of inertia as a function of the radius Specification [1] investigation of the inertia of various bodies in rotational motion [2] hollow cylinder, solid cylinder or rotating bar with masses as a rotating body [3] generate a uniformly accelerated rotational motion via weight, pulley and cable drum [4] rotating bar: adjustable position of the mass to realise different radii [5] measure the time and the acceleration distance [6] position and fix the parts via table clamps Technical data Rotating bar - length: 550mm - masses: 2x 0,1kg, 2x 0,2kg, 2x 0,4kg Solid cylinder - diameter: 120mm - mass: 0,9kg Hollow cylinder - outer diameter: 120mm - inner diameter: 110mm - mass: 0,9kg Weight for the drive - 1N LxWxH: 730x180x480mm (set-up) Weight: approx. 13kg
