Slenderness Ratio of a Wood Column
Easywoodcolumnsslenderness
A solid rectangular wood column has a specified effective length ℓe = 96 in and a least actual cross-section dimension dmin = 3.5 in. What is the slenderness measure ℓe/dmin?
- A27.4
- B95.0
- C2.29
- D0.0365

Answer: A. 27.4
The question defines the measure as effective length over least dimension: 96/3.5 = 27.43. 95.0 uses ℓe/r with r = d/√12 = 1.01 in, the radius-of-gyration measure, which is not the one requested. 2.29 mixes units by using 8 ft over 3.5 in. 0.0365 inverts the ratio (3.5/96).
