A bifilar suspension arrangement is a setup used to determine the moment of inertia of an object by suspending it using two parallel threads or wires. The suspended body oscillates in a horizontal plane, and its period of oscillation helps in calculating the moment of inertia. This method is widely used in physics experiments, mechanical engineering, and metrology to study rotational motion. The bifilar suspension system ensures minimal friction and external interference, providing accurate measurements. It is commonly applied in laboratories for precision analysis of rigid bodies, aiding in research, design, and engineering studies related to dynamics and motion.
