1. Ergonomics is best defined as:
A. The study of machinery efficiency
B. The design of tools for maximum strength
C. The science of fitting work to the worker
D. The prevention of industrial accidents
Rationale: Ergonomics focuses on optimizing the fit between people,
tasks, and environments to improve safety, comfort, and performance.
2. The primary goal of ergonomics is to:
A. Increase production costs
B. Reduce training time only
C. Improve human well-being and system performance
D. Replace workers with automation
Rationale: Ergonomics aims to enhance both human health and overall
system efficiency.
3. Which discipline contributes most directly to physical ergonomics?
A. Sociology
B. Biomechanics
C. Economics
D. Anthropology
, Rationale: Biomechanics studies forces and movements of the human
body relevant to physical work.
4. Anthropometry refers to:
A. Measurement of workplace hazards
B. Measurement of human body dimensions
C. Study of muscle fatigue
D. Analysis of posture
Rationale: Anthropometry provides body size data for design decisions.
5. Which percentile range is commonly used in ergonomic design?
A. 1st–99th
B. 5th–95th
C. 10th–90th
D. 25th–75th
Rationale: Designing for 5th–95th percentiles accommodates most users.
6. Static work is characterized by:
A. Continuous joint movement
B. Sustained muscle contraction
C. Alternating muscle use
D. High metabolic demand
Rationale: Static work involves holding postures with little movement.
7. Dynamic work involves:
A. Fixed postures
B. Rhythmic muscle contraction and relaxation
C. No energy expenditure
D. Minimal circulation
Rationale: Dynamic work promotes blood flow and reduces fatigue.
8. The neutral posture principle suggests:
A. Extreme joint angles
B. Joints positioned near mid-range
C. Locked joints
, D. Asymmetric alignment
Rationale: Neutral postures minimize musculoskeletal stress.
9. Repetitive strain injuries are most associated with:
A. Low force, low repetition
B. High repetition with inadequate recovery
C. High variability tasks
D. Cognitive overload
Rationale: Repetition without rest increases injury risk.
10.The primary risk factor for low back pain at work is:
A. Noise exposure
B. Manual material handling
C. Screen glare
D. Lighting color
Rationale: Lifting, pushing, and pulling contribute significantly to back
injuries.
11.The NIOSH lifting equation is used to:
A. Measure posture
B. Assess lifting task risk
C. Evaluate lighting
D. Design seating
Rationale: It estimates recommended weight limits for lifting.
12.A coupling factor in lifting refers to:
A. Load weight
B. Quality of grip on the object
C. Lifting frequency
D. Lifting height
Rationale: Good coupling reduces hand and back stress.
13.Cognitive ergonomics focuses on:
A. Tool design
B. Mental processes such as perception and decision-making
