Question 1

What is the recommended monitor viewing distance at a seated computer workstation?

Accepted Answer

20–28 inches

Answer

A viewing distance of 20–28 inches from the eyes to the monitor reduces eye strain and maintains a comfortable neck and head posture.

Question 2

For seated desk tasks, the optimal height of the work surface relative to elbow height is:

Accepted Answer

Approximately even with or just below elbow height

Answer

Work surfaces at or just below elbow height (approximately 7–10 inches above seat) allow arms to rest in a neutral position, reducing shoulder and wrist fatigue.

Question 3

Per ADA guidelines, what is the minimum clear width required for an accessible single-loaded corridor?

Accepted Answer

36 inches

Answer

ADA requires a minimum 36-inch clear corridor width to allow unobstructed wheelchair passage in a single-direction path.

Question 4

In ergonomic theory, 'neutral posture' is defined as:

Accepted Answer

Body alignment that minimizes stress on muscles, joints, and the spine

Answer

Neutral posture positions the body with joints in mid-range and the spine in its natural curves, minimizing musculoskeletal load and reducing injury risk.

Question 5

Reference guides such as Neufert's Architects' Data are used by interior designers primarily to:

Accepted Answer

Access standardized human dimension data for space planning

Answer

Neufert's Architects' Data and similar references compile standardized anthropometric and functional dimension data that designers use to ensure human-scaled, usable spaces.
