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

1st to 99th percentile

Answer

25th to 75th percentile

Answer

10th to 90th percentile

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

The maximum reach distance achievable with full body lean

Answer

The horizontal distance from shoulder to fingertip at full extension

Answer

The overhead reach measured from the floor to extended fingertip

Question 3

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

Accepted Answer

Standing body height from floor to top of head

Answer

Shoulder height in a seated position

Answer

Eye height measured from the floor

Answer

Trunk length from seat surface to top of 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 data covers seated workers while dynamic data covers standing workers

Answer

Dynamic data is collected from injured workers to guide accommodation

Answer

Static data applies only to male workers while dynamic data applies to female workers

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

To simulate the cost of a proposed ergonomic intervention

Answer

To replace physical prototypes entirely during product development

Answer

To calculate the RULA score automatically from CAD drawings

Question 6

When designing for gender diversity on an assembly line, which approach best ensures accommodation of both male and female workers?

Accepted Answer

Design adjustability into the workstation to cover 5th percentile female to 95th percentile male

Answer

Design for the average male worker and provide step stools for shorter workers

Answer

Design for the 95th percentile male to ensure everyone fits

Answer

Use separate workstations for male and female workers
