Question

In motion study, the "Therblig" symbol (Image) represents:

• A. Find
• B. Search
• C. Assembly
• D. Inspection

Hint:

The symbol looks like an Eye. You use your eyes to Find things! Just remember that Search is the "looking" phase, while Find is the "moment of discovery" where the eye stops moving.

Answer 1

The Correct Option is A

In industrial engineering and work study, "Therbligs" are a system of 18 elemental motions used to analyze manual tasks. The term "Therblig" was coined by Frank and Lillian Gilbreth, who were pioneers in motion study. 1. Symbol Analysis: The symbol provided in the question—a stylized eye fixed on an object—is the standard industrial engineering representation for the Therblig

"Find".

2. Defining "Find": "Find" represents the mental reaction that occurrs at the exact end of the "Search" element. It is the moment in time when the eyes or hands successfully locate the object they were looking for.

• Search: The eye "hunting" for an object (Symbolized by an eye looking around).

• Find: The moment the object is identified and focused upon (The symbol in the question).

3. Role in Efficiency: In micro-motion analysis, "Find" is classified as an

ineffective Therblig because it is a mental process that does not physically add value to the product. Industrial engineers try to eliminate "Find" and "Search" by organizing the workplace so that every tool and part has a standardized, known location.
