Micromotion study is formally defined as__________________?
Show answer Hide answer
Answer: A. analysis of a man-work method by using a motion picture camera with a timing device in the field of view
Explanation
Micromotion study examines worker movements in fine detail using specialized recording equipment. It requires a motion picture camera combined with a timing device in the field of view. This setup allows industrial engineers to analyze every elemental motion of a task. Frank and Lillian Gilbreth pioneered micromotion studies using therbligs to classify motions. Time-measuring devices like micro-chronometers captured elapsed time directly on film frames. Detailed film analysis helps eliminate wasteful movements and reduce operator fatigue.
High-speed or repetitive manufacturing operations benefit significantly from micromotion analysis. Engineers use these studies to design ergonomic workstations and improve assembly methods. Optimizing worker motions increases overall productivity and reduces repetitive strain injuries. Option B is vague and fails to mention the crucial use of motion picture cameras. Option C describes general motion study without specifying photographic timing techniques. Option D describes simultaneous motion cycles rather than the specific filming methodology.
