What term refers to the practice of designing machines, products, and workplaces to fit people's sizes and capabilities?

• A. Ergonomics
• B. Biomechanics
• C. Industrial design
• D. Cognitive ergonomics

Answer: (A)

Ergonomics focuses on designing machines, products, and workplaces to fit people’s sizes and capabilities. It uses knowledge of body dimensions, reach limits, strength, and posture to create comfortable, safe, and efficient interactions. By adjusting features like chair height, control placement, tool handles, and workspace layout to match users, ergonomics aims to reduce strain and the risk of injury while boosting performance.

Biomechanics, while related, studies the forces and movements of the body itself rather than tailoring designs to fit those movements. Industrial design is broader and centers on the overall look, feel, and usability of a product, not specifically on matching it to human dimensions. Cognitive ergonomics deals with mental processes—perception, memory, decision-making—rather than physical fit.
