Question 1

What is the primary goal of ergonomics in industrial engineering?

Accepted Answer

Fitting the work environment to the capabilities and limitations of the worker

Answer

Ergonomics aims to design work systems, tools, and environments that match human capabilities to reduce injury risk and improve efficiency.

Question 2

Which type of musculoskeletal disorder is most commonly associated with repetitive motions on assembly lines?

Accepted Answer

Cumulative trauma disorders (CTDs)

Answer

Cumulative trauma disorders develop gradually from repeated micro-injuries caused by repetitive motions, awkward postures, or excessive force.

Question 3

What anthropometric measure is most commonly used to design workstation heights?

Accepted Answer

Elbow height in standing position

Answer

Elbow height in the standing position is the primary reference for setting work surface heights to minimize shoulder and back strain.

Question 4

The NIOSH lifting equation provides a recommended weight limit (RWL) based on which set of task variables?

Accepted Answer

Horizontal distance, vertical height, travel distance, asymmetry, frequency, and coupling

Answer

The NIOSH equation uses six task factors—horizontal distance, vertical height, vertical travel, asymmetry angle, lift frequency, and hand-to-object coupling—to calculate the RWL.

Question 5

What does a 5th percentile design approach mean in ergonomics?

Accepted Answer

The design is based on the smallest 5% of the target population to ensure reach requirements are met

Answer

Designing to the 5th percentile for reach-critical dimensions ensures that even the smallest users can access controls or reach work objects.
