What is ergonomics?

• A. Science of designing the job to fit the worker rather than physically forcing the worker's body to fit the job.
• B. The process of evaluating machine efficiency.
• C. The study of environmental noise levels.
• D. The method of distributing tasks among teams.

Answer: (A)

Ergonomics is about shaping the work to fit the person, reducing awkward postures and excessive forces so tasks can be done safely and comfortably. The correct answer captures this idea: the job is designed to fit the worker rather than forcing the worker to fit the job. In practice, ergonomics means adjustable workstations, appropriately sized hand tools, screens and keyboards at proper heights, and layouts that minimize reaching, twisting, or repetitive motions. When done well, it lowers the risk of musculoskeletal injuries and can improve speed and accuracy. It isn’t about evaluating machine efficiency, environmental noise, or how tasks are distributed among teams; those concern equipment performance, noise control, and work management respectively.
