Difficulty: Easy
Correct Answer: Straight stair
Explanation:
Introduction / Context:
Comfort in stair design depends on uniform treads/risers, clear sight lines, and simple movement patterns. For everyday buildings, ease of ascent and descent across all ages is important.
Given Data / Assumptions:
Concept / Approach:
Straight stairs provide the simplest movement: users proceed in a single direction with uniform goings and risers, and a continuous handrail. There are no triangular winders or turning landings that force gait adjustment, making them the most comfortable for most users.
Step-by-Step Solution:
Compare stair types by uniformity and gait consistency.Identify that straight stairs avoid variable tread widths common in winders.Conclude that straight stairs generally offer the best comfort.
Verification / Alternative check:
Ergonomic guidance and many architectural texts recommend straight stairs for maximum comfort and safety, provided space permits.
Why Other Options Are Wrong:
Common Pitfalls:
Equating architectural elegance with comfort; neglecting consistent riser/going proportions and adequate handrail design.
Final Answer:
Straight stair
