The video explains how objects naturally vibrate when given an initial impulse and discusses engineering techniques, such as damping devices, used to prevent the buildup of harmful vibrations at resonant frequencies.

What happens to an object when it is given an initial impulse?

• It naturally vibrates.

• It changes color.

• It remains stationary.

• It disintegrates.

What is the primary purpose of damping devices in engineering?

• To increase the speed of machines.

• To enhance the color of materials.

• To cool down engines.

• To manage and reduce vibrations.

Which of the following is NOT a technique used to manage vibrations?

• Isolation techniques

• Vibration amplification

• Resonant frequency tuning

• Damping devices

Why is it important to prevent the build-up of vibrations at resonant frequencies?

• To increase sound quality.

• To enhance visual appeal.

• To avoid structural damage.

• To save energy.

What can happen if vibrations are not properly managed in engineering structures?

• They can become more efficient.

• They can cause damage over time.

• They can reduce costs.

• They can improve performance.
