Balancing by lowering the center of mass Steps: - Identify the balance point: The toy balances on the rod's end, so the pivot is at the top of the rod. - Locate the center of mass: For stability, the center of mass must be directly above or at the pivot to prevent tipping. - Role of weights: Added weights at the base shift the overall center of mass downward. - Achieve equilibrium: Lowering the center of mass below the pivot creates a stable configuration where torque keeps it upright. Why C is correct: - The center of mass is the point where the object's weight acts; lowering it below the pivot ensures gravitational torque restores balance if tilted, per the stability principle for inverted pendulums. Why the others are wrong: - A: Pressure is force per area, unrelated to balancing; weights affect torque, not pressure directly. - B: Increasing total weight adds mass but doesn't specify position, so it doesn't ensure balance without lowering the center of mass. - D: Raising the center of mass above the pivot would make …
