Question

Which of the following is a moving picture technique developed by Mundel?

• A. Therbligs
• B. Memomotion
• C. Micromotion
• D. Hand and body motion

Hint:

Associate "Mundel" with "Memomotion" (both start with the letter M).
Mundel developed Memomotion to analyze long, repetitive tasks at a lower frame rate to save film and analysis time.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Work simplification and motion study techniques analyze human movement during work to reduce fatigue, save energy, and increase efficiency.
Specialized photographic and filming techniques are used to study and record these motions in detail.

Step 2: Detailed Explanation:
Memomotion (or memo-motion) study is a time-lapse film technique developed by Marvin E. Mundel in 194
It involves filming a task or work process using a motion picture camera set at a slow, constant frame rate (typically 50 or 100 frames per minute, instead of the standard 960 or 1000 frames per minute used in normal films).
This technique allows researchers to analyze long-cycle work, group activities, or multi-person operations efficiently by reviewing compressed, frame-by-frame records of the tasks.
Therbligs, developed by Frank and Lillian Gilbreth, are a system of 17 basic hand and body movements used to analyze work tasks, but they are not a filming technique.
Micromotion study is another Gilbreth technique that uses high-speed filming to analyze rapid, short-duration movements.

Step 3: Final Answer:
The moving picture technique developed by Marvin E. Mundel is Memomotion.
