The Ergonomic Stress equation is defined by which three components?

Ergonomic stress comes from how the worker, the surroundings, and the job interact. The three components are: the physical setting—the actual workspace conditions such as temperature, lighting, noise, vibration, space, and equipment layout; the worker’s relationship to the setting—the fit between the person and the environment, including posture, reach, strength, training, and how the worker uses tools and controls; and the task requirements—the demands of the job like pace, repetition, force, duration, and complexity. Together, these elements shape how much strain the body experiences: a harsh environment can be manageable with a good fit and reasonable task demands, while mismatches or overly demanding tasks increase ergonomic stress. The other options only capture one aspect (environment only, or personal factors, or general health) and miss the full interaction among environment, human-system fit, and task demands.
