Ergonomics Exam Solutions
Course Introduction
Ergonomics is the study of designing workplace environments, systems, and products that fit the physical and cognitive abilities of users to enhance comfort, efficiency, and safety. This course explores the principles of human factors engineering, focusing on optimizing the interaction between people and their workspaces. Topics include anthropometry, biomechanics, workplace assessment, risk factor analysis, and the prevention of occupational injuries. Students will learn to evaluate workstations, design ergonomic interventions, and apply evidence-based solutions to real-world scenarios across various industries.
