Ix

Moment of inertia about the X axis (torsion)

Iy

Moment of inertia about the Y axis (bending)

Iz

Moment of inertia about the Z axis (bending)

Ay

Shear rigidity factor (reduced sectional area for calculations of shear deformations) in the Y axis direction

Az

Shear rigidity factor (reduced sectional area for calculations of shear deformations) in the Z axis direction

Wx

Section modulus for calculations of torsion stresses

Wy

Shear area (reduced extreme shear stress coefficient) in the direction of Y axis (Qy)

Wz

Shear area (reduced extreme shear stress coefficient) in the direction of Z axis (Qz)

Wply

Plastic section modulus in bending about the Y axis

Wplz

Plastic section modulus in bending about the Z axis

Sp

Painting surface of the unit length

m

Unit weight per unit length

Iomega

Warping constant.
