TM 162 Bifilar/Trifilar Suspension Of Pendulums Didactic Equipment Vocational Training Equipment Mechanical Training Equipment
Moments of inertia of different bodies in a rotary pendulum experiment Features - ideal mathematical pendulum can be demonstrated - moment of inertia in an experiment on a rotary pendulum Learning objectives/experiments - influence of thread length on the oscillation period - determine the mass moment of inertia Specification [1] investigation of the vibration behaviour of various pendulum bodies in bifilar and trifilar suspension [2] investigation of a mathematical pendulum (bifilar) and a physical pendulum (trifilar) [3] choice of three pendulum bodies: beam, cylinder, circular ring [4] change the thread length with a clamping device [5] stopwatch to measure the oscillation period [6] determine the mass moment of inertia [7] bracket for wall mounting Technical data Pendulum bodies - beam -- LxWxH: 40x40x160mm -- mass: 2kg - cylinder -- diameter: 160mm -- height: 19mm -- mass: 3kg - circular ring -- outer diameter: 160mm -- inner diameter: 100mm -- height: 41mm -- mass: 4kg Thread length: up to 2000mm Stopwatch: 1/100s LxWxH: 205x200x2000mm Weight: approx. 12kg
