SUMMARY
The problem involves determining the position to hang a mass of 1.42M on an asymmetrical ruler balanced at the 40.9 cm mark, with another mass M hung at the 100 cm mark. The correct torque equation is established as 1.42Mg(40.9 - x) = Mg(100 - 40.9), leading to the solution x ≈ 41.6 cm. However, an incorrect approach yields a negative value of x ≈ -0.72 cm, indicating a misunderstanding of the torque balance principle. The discrepancy highlights the importance of correctly applying torque equations in equilibrium problems.
