Algor Solution for Beam Analysis

Definitions:

A	cross-sectional area
Sa2	Shear area in local 2 direction
Sa3	Shear area in local 3 direction
J1	Torsional constant about 1-axis
I2	Moment of inertia about 2-axis
I3	Moment of Inertia about 3-axis
S2	Section modulus about the 2-axis (I2/c)
S3	Section modulus about the 3-axis (I3/c)

Sa2 and Sa3 are equal zero unless the beam is very short and stocky.

Axis 1 is along i and j nodes.

Nodes i, j, k define plane. Axis 2 is normal to axis 1 and lies in the plane of ijk.
