Ergonomics is defined as which of the following?

• A. The study of fuel efficiency in aircraft engines.
• B. An applied science concerned with designing and arranging things people use so that the people and things interact most efficiently and safely.
• C. A field focused on athletic performance and training.
• D. The science of managing the body's energy and endurance.

Answer: (B)

Ergonomics is the study of designing and arranging things people use so that the people and the things interact most efficiently and safely. This means things like where controls sit on a device, how a chair supports your back, or how a workstation is organized so you can work comfortably without strain and with fewer mistakes. The idea is to tailor the environment and tools to fit the person, not force people to adapt to awkward setups. For example, an airplane cockpit layout that places important switches within easy reach and at the right height helps pilots operate safely and with less fatigue. The other options describe completely different fields: fuel efficiency in engines is propulsion engineering, athletic performance is sports science, and managing the body’s energy and endurance is physiology or exercise science.
