Research and Practical Design of a Teaching Experiment for an Unbalanced Rod Based on the Principle of Gravity Balance

Abstract

This paper introduces a teaching experiment design for an unbalanced rod based on the principle of gravity balance. This unbalanced rod is a purely mechanical mobile rod-balancing mechanism characterized by simplicity in structure, low cost, high efficiency, and reliable safety. The structure is comprised of a ladder frame, rocker, support rod, and a multi-stage adjustable self-locking system. An automatic correction device controls the direction and telescoping length of the support rod by managing the double rocker and shifting the center of gravity to stabilize the unbalanced rod. Experimental data indicates that this design effectively counters external forces on the rod, maintaining stability. This device holds potential for broad applications, such as in stable support structures, industrial tipping alarms, and automatic correction systems.
