Design Tech - Topic 1.1a

What is the main goal of ergonomics in design?

• To improve system reliability and maintenance.

• To maximize the aesthetic appeal of products.

• To align product design with environmental sustainability.

• To optimize the interaction between people and systems for efficiency and comfort.

Which of the following does Human Factors aim to achieve?

• Increasing the complexity of design systems.

• Reducing errors and improving safety in product usage.

• Enhancing the product's environmental impact.

• Creating systems solely for aesthetic purposes.

What is a key characteristic of dynamic anthropometric data?

• It measures a subject when being still.

• It considers body movements during tasks.

• It only includes skeletal measurements.

• It is easier to collect than static data.

When designing an airplane cockpit, which percentile group is most critical to consider for arm reach?

• 95th percentile

• 50th percentile

• 5th percentile

• 25th percentile

Which of the following tools is commonly used to collect static anthropometric data?

• Laser rangefinders

• Skinfold calipers

• Inclinometers

• Accelerometers

What does the 95th percentile range represent in anthropometric studies?

• The value below which 5% of the population falls

• The value below which 95% of the population falls

• The range within which all population sizes fit.

• The midpoint dimension of the population.

If designing door heights for a building, which percentile is most relevant to ensure usability for most users?

• 50th percentile

• 5th percentile

• 95th percentile

• 75th percentile

In designing an emergency exit, what does clearance primarily consider?

• The shortest user's ability to reach the door.

• The widest user's ability to pass through the space.

• The average duration of all potential users to reach the exit.

• The safety considerations related to the use of the exit

The workspace envelope is determined by:

• The user's skeletal dimensions.

• The user's functional limbs reach.

• The user's functional arms reach.

• The maximum height the user can reach while seated.

A major disadvantage of using primary anthropometric data is:

• Lack of specificity to the target audience.

• High cost and time requirements for collection.

• Limited access to specialized measuring tools.

• Dependence on outdated research data.
