# ANGLE WITH UNEQUAL LEGS - SECTION PROPERTIES CALCULATOR

Section properties calculator for angle with unequal legs. Area, distances from the centroidal axes to the back of the legs, second moment of area and radius of gyration about the centroidal axes are calculated section properties.

Section properties formulas are given below the calculator.

### Definitions:

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.

### List of Equations:

 ANGLE WITH UNEQUAL LEGS Parameter Symbol Equation Cross section area A A = t(b + d - t) Area moment of inertia Ix Ix = 1/3*[bd3 - (b-t) * (d-t)3] - A * (d - yc)2 Area moment of inertia Iy Iy = 1/3*[db3 - (d-t) * (b-t)3] - A * (b - xc)2 Distance from the centroid to the back of the long leg xc xc=(b2+dt-t2)/(2*(b+d-t)) Distance from the centroid to the back of the short leg yc yc=(d2+bt-t2)/(2*(b+d-t)) Mass M M = ALρ Radius of gyration rx rx = (Ix/A)^0.5 Radius of gyration ry ry = (Iy/A)^0.5
