SUMMARY
In torque calculations involving a suspended bar, such as a meter stick, the mass of the bar can be ignored when it is negligible compared to the weights hanging from it. This condition is satisfied when the total mass of the hanging weights significantly exceeds the mass of the bar itself. Additionally, if the bar is suspended at its center, the mass is evenly distributed, which further justifies ignoring its weight in torque calculations.
