1. What is the related technological concepts?Vibration damping, acoustic insulation, composite materials, viscoelasticity
2. Why did trains use paper wheels?Paper wheels were used to reduce the noise and vibrations that passengers felt when trains moved. They let passengers enjoy a quieter and more comfortable ride, especially on luxury Pullman cars.
3. How do paper wheels make trains quieter?The paper layers compress and bend when the wheel rolls, turning the motion into heat and stopping sound from traveling into the car. This keeps the train’s interior calm and peaceful.

Viscoelastic Material: A material that exhibits both viscous (fluid-like) and elastic (solid-like) properties when undergoing deformation.
Laminated Structure: A material made by bonding together multiple layers of the same or different materials.
Attenuate: To reduce the force, effect, or value of something, particularly sound or signals.
