Final answer:
To find the short radius of gyration for wide flanges, use the equation r = sqrt(I/A), where r is the short radius of gyration, I is the moment of inertia, and A is the cross-sectional area.
Step-by-step explanation:
The short radius of gyration for wide flanges can be found using the equation:
r = sqrt(I/A)
where r is the short radius of gyration, I is the moment of inertia about the axis perpendicular to the flanges, and A is the cross-sectional area of the flanges.
For example, if a wide flange has a moment of inertia of 500 cm^4 and a cross-sectional area of 75 cm^2, the short radius of gyration would be calculated as:
r = sqrt(500 cm^4 / 75 cm^2) = 8.66 cm
