SUMMARY
The discussion centers on the application of the Principle of Moments to balance a meter rule. Given a mass of 5 kg placed 40 cm from the pivot, the required mass to balance the rule at 30 cm from the pivot is calculated to be 6.66 kg. The equation used is M1 * G * D1 = M2 * G * D2, where G is the acceleration due to gravity (9.8 m/s²). The solution confirms that the calculated mass of 6.66 kg is correct.
