Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the measurement units?Imbalance is quantified in ounce-inches (oz-in) or gram-centimeters (g-cm)
2. What is the balancing equipment?Static balancers address single-plane imbalances, while dynamic balancers address two-plane imbalances
3. What is tire balance and why does it matter for a smooth ride?Tire balance means making sure the weight in a wheel is spread evenly. If it isn’t, the wheel can wobble and make the car shake, especially at higher speeds.
4. Why do cars shake more when they go faster if the wheels are unbalanced?Because the force from the uneven weight gets stronger as the wheel spins faster. The faster the wheel turns, the bigger the shaking.

Centrifugal Force: An apparent outward force experienced by an object moving in a circular path.
Resonance: The phenomenon where a system vibrates with maximum amplitude when driven at its natural frequency.
Wheel Rim: The outer edge of a wheel, where the tire is mounted.
