CIEE CIEE Anthropometry & Human Factors

Question 1

Which anthropometric percentile range is typically used when designing workstations to accommodate the widest range of workers?

Accepted Answer

5th to 95th percentile

Answer

The 5th to 95th percentile range is the standard design target, ensuring workstations fit the vast majority of the workforce without extreme over-engineering.

Question 2

What is 'functional reach' in the context of industrial ergonomics?

Accepted Answer

The reach distance attainable while maintaining a stable, supported posture

Answer

Functional reach refers to the distance a worker can reach while maintaining a stable and balanced posture, which is more practical for workstation design than maximum anatomical reach.

Question 3

In anthropometric data, what does 'stature' refer to?

Accepted Answer

Standing body height from floor to top of head

Answer

Stature is the standard anthropometric term for total standing height measured from the floor to the top of the head.

Question 4

Why is it important to consider both static and dynamic anthropometry when designing workstations?

Accepted Answer

Static data captures body dimensions at rest while dynamic data captures ranges of motion during tasks

Answer

Static anthropometry provides fixed body measurements, while dynamic anthropometry accounts for the changes in body dimensions and reach envelopes during movement and task performance.

Question 5

What is the primary purpose of a 'manikin' or digital human model in ergonomic workstation design?

Accepted Answer

To visually represent different anthropometric percentiles and evaluate fit within a virtual workspace

Answer

Digital human models allow ergonomists to visualize how workers of different sizes will interact with a workstation design before physical construction, identifying clearance and reach issues early.
