Practice Questions

Test your understanding with targeted questions

Question 1 Easy

If you are designing the height of a doorway, which specific anthropometric measurement should you use?

  • Answer: Stature (Total Height).
  • Hint: You need to ensure the tallest users don't hit their heads.

💡 Hint: You need to ensure the tallest users don't hit their heads.

Question 2 Easy

What is the difference between Static and Dynamic anthropometry?

  • Answer: Static anthropometry measures the body in a fixed, stationary position (like arm length while standing still). Dynamic anthropometry measures the body during movement (like the maximum distance a person can reach while sitting).
  • Hint: Think "Still" vs. "Action."

💡 Hint: Think "Still" vs. "Action."

Question 1

Which measurement is used to determine the width of a public transit seat?

  • Type: mcq
  • Options: A) Stature, B) Shoulder Breadth, C) Hip Breadth, D) Hand Length
  • Correct Answer: C (though B is used for the backrest, Hip Breadth determines the actual seat pan).
A) Stature
B) Shoulder Breadth
C) Hip Breadth
D) Hand Length * **Correct Answer**: **C** (though B is used for the backrest
Hip Breadth determines the actual seat pan).

Question 2

True or False: Designing for the "Average" (50th percentile) user is the best way to ensure everyone is comfortable.

  • Type: boolean
  • Options: True, False
  • Correct Answer: False
  • Explanation: A 50th percentile design will be too big for the bottom 49% and too small for the top 49%. Adjustability is required to fit a wider range.

Challenge Problems

Challenge 1 Hard

The Workplace Audit: A factory worker reports chronic back pain. They spend 8 hours a day standing at a packing station.

  • Task: Identify one anthropometric data point you would measure to fix the station and one design solution (from the "Design Guidelines" section).
  • Solution: Measure the worker's Elbow Height. The solution is Adjustability—installing a height-adjustable platform or table so the worker can align the station to their specific elbow height.
  • Hint: Look at the "Static Anthropometry" table in the summary.

💡 Hint: Look at the "Static Anthropometry" table in the summary.

Challenge 2 Hard

The 5th Percentile Challenge: You are designing a high-mounted emergency "Stop" button for a factory machine.

  • Task: Should you use the 5th percentile female arm reach or the 95th percentile male arm reach to determine the maximum height of the button? Justify your answer.
  • Solution: Use the 5th percentile female arm reach. If the person with the shortest reach (5th percentile) can reach the button, then everyone taller than them (including the 95th percentile) will also be able to reach it. If you used the 95th percentile, shorter users would be unable to stop the machine in an emergency.
  • Hint: In safety, always design for the "limiting" user (the one who has the most difficulty reaching).

💡 Hint: In safety, always design for the "limiting" user (the one who has the most difficulty reaching).
