Therblig symbols are used in motion study to classify basic elemental motions. Each symbol corresponds to a specific activity performed by a worker.
In this question, four symbols labeled P, Q, R, and S must be matched with four meanings: rest to overcome fatigue, avoidable delay, inspect, and search.
Step 1: Symbol P.
The first symbol resembles an eye-shaped ellipse, which is associated with the action "Search," because it visually represents scanning or looking around. Hence P corresponds to 4.
Step 2: Symbol Q.
This symbol is a simple vertical oval, representing the act of "Inspect," which involves a focused check. Thus Q corresponds to 3.
Step 3: Symbol R.
This shape shows a circle with a step-like tail, representing "Rest for overcoming fatigue," which matches meaning 1.
Step 4: Symbol S.
The last symbol resembles a horizontal line with a small loop at one end, representing "Avoidable delay," which matches meaning 2.
So the correct matching is P-4, Q-3, R-1, S-2.
