Which term includes the research and analysis of the mechanics (operation of our muscles, joints, tendons, etc.) of our human body. It also includes Force (impact on user's joints), Repetition, Duration and Posture.

• A. Biomechanics
• B. Biomechanics in Human factors
• C. Anthropometrics
• D. Dynamic data

Answer: (B)

The main idea here is how the body moves and the forces acting on it, and how that understanding is used in designing for people. Biomechanics covers the study of how muscles, joints, tendons, and other body parts work together, including the forces that impact joints, the effects of repetition, duration of activity, and posture. When this biomechanical knowledge is applied within the field of human factors, it becomes about using those insights to improve how people interact with tools, interfaces, and work environments—everything from reducing injury risk to optimizing performance. That combination—mechanical analysis of the body plus its application to design and task-related factors like force, repetition, duration, and posture—best fits the described scope.

Biomechanics alone focuses on movement and forces, but without the explicit design/interaction context. Anthropometrics deals with body size and shape, not movement mechanics. Dynamic data refers to data about movement but isn’t a field name in itself.
