Definitions:

Equilateral Triangle: A triangle with all three sides of equal length.

Second Moment of Area: The capacity of a cross-section to resist bending.

Radius of Gyration (Area): The distance from an axis at which the area of a body may be assumed to be concentrated and the second moment area of this configuration equal to the second moment area of the actual body about the same axis.

Parameter Symbol Equation
Cross section area A A = b*h/2
Altitude h h=(a2-(b2*1/4))0.5
Area moment of inertia Ix Ix = (b*h3)*1/36
Area moment of inertia Iy Iy = (h*b3)*1/48
Distance from the centroid to
the back of the long leg
xc xc=b/2
Distance from the centroid to
the back of the short leg
yc yc=h*2/3
Radius of gyration rx rx = 0.2357*h
Radius of gyration ry ry机机对机机小视频教程 = 0.2041*b
