In a cantilevered steel beam supporting a balcony, which consequence arises when sustained vibrations match its natural frequency?

💡 Explanation

Resonance causes increasing amplitude in the beam, driven by positive feedback, leading to failure, because the beam accumulates energy with each vibration cycle. Therefore, the beam collapses, rather than distributing the load, damping vibrations, or decreasing the deflection.

• Which consequence results when an HVAC system's variable-speed compressor pump experiences excessive cycling?
• Which outcome occurs when a scroll compressor in a heat pump operates with superheated refrigerant at the inlet?
• Which failure occurs when chromatic dispersion exceeds acceptable limits in a fiber optic link employing dense wavelength division multiplexing (DWDM)?
• Which risk increases when investment casting is performed without adequate degasification?
• Which outcome occurs when a three-phase power transformer experiences an internal winding short circuit with delayed breaker response?
• Which outcome occurs when lean fuel mixtures combust in a turbocharger?
