Which item is NOT an energy absorber?

• A. Cross deck pendant
• B. Tape drum absorber
• C. Rotor
• D. Housing assembly

Answer: (A)

Energy absorbers dissipate energy during impact to limit peak loads on the structure. The cross deck pendant is a load‑bearing link that simply transmits forces and supports the deck; it isn’t designed to absorb energy. In contrast, a tape drum absorber is built to dissipate energy through controlled friction as tape is pulled from a drum, reducing deceleration forces. A rotor can be a moving element within an absorber, contributing to energy dissipation through resistance, and a housing assembly provides the enclosure and alignment for the absorber components, containing and guiding the energy-absorbing mechanism. Because of this, the cross deck pendant is the item that does not function as an energy absorber.
