Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

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

1. How big is Centrifugal pendulum absorber?Internal combustion engine drive trains (automotive, marine, industrial)
2. What is the primary function?To attenuate torsional vibration amplitudes in rotating machinery, especially engine drive trains
3. What is the engineering impact?Enhances component durability, reduces noise and harshness, and improves overall system reliability
4. How does the pendulum absorber stop engine vibrations?The pendulums are tuned to swing at the same speed as the engine's bad vibrations. When they swing, they absorb the energy and make the engine feel calmer.
5. Why do engines need a centrifugal pendulum absorber?Engines make uneven bursts of power that can shake the crankshaft and parts of the car. The absorber reduces those shakes, so parts last longer and the ride is quieter.

Torsional Vibration: Rotational oscillations or twisting motions occurring around an axis of rotation.
Centrifugal Force: An inertial force acting radially outward on a body in a rotating frame of reference.
Tuned Mass Damper: A passive vibration-reducing device consisting of a secondary mass attached to the primary structure.
