Explanation:

Flexural Torsional Buckling Strength of Single Angle in Compression

The flexural torsional buckling strength of a single angle loaded in compression through one of its legs is evaluated using the equivalent slenderness ratio. This slenderness ratio is influenced by several factors; however, it does not depend upon the edge to edge length of the supporting member.

Analyzing the Given Options

1. "Yield stress ratio." (Relevant Factor)

   • The yield stress ratio affects the buckling strength as it determines the material's ability to withstand stress before yielding.

2. "Width of the two legs of the angle." (Relevant Factor)

   • The width of the legs affects the cross-sectional properties and thus influences the buckling strength.

3. "Radius of gyration about the minor axis." (Relevant Factor)

   • The radius of gyration about the minor axis is a key geometric property that directly affects the slenderness ratio and buckling strength.

4. "Edge to edge length of the supporting member." (Not a Relevant Factor)

   • The edge to edge length of the supporting member does not influence the slenderness ratio of the angle itself.

   • Therefore, it is not a factor that affects the flexural torsional buckling strength of the angle.
