Question 1 of 27070

Resonant vibrations, which can cause machinery failure, occur when which of the following conditions happen?

🔍 Key Concepts

• Natural frequency vs forced (external) vibration • What resonance means in mechanical systems • How matching frequencies affect vibration amplitude

💭 Think About

• Which option describes a situation where an outside repeating force is acting on machinery that already has its own natural frequency? • Look for the choice that clearly connects an external/forced vibration with a match to the machinery’s natural frequency. • Which options only restate what natural or free vibration are, without involving an external periodic force?

✅ Before You Answer

• Identify which choice mentions an external or forced vibration/frequency acting on the machinery. • Check if the option explicitly or implicitly involves the matching of the external frequency with the machinery’s natural frequency. • Eliminate any answer that talks about natural or free vibration without linking it to an external periodic force.

Question 1 of 27070

Resonant vibrations, which can cause machinery failure, occur when which of the following conditions happen?

The machinery is operated at the natural frequency with no external forces in play.

A forced frequency is placed on a piece of operating machinery.

The natural frequency of the machinery is the same as the free vibration frequency.

The frequency of an external vibration is the same as one of the natural frequencies of the machinery.
