Calculate trapezoidal beam cross section properties.
Axis L is parallel to the base. Axis M is perpendicular to the base. Axis 1 and 2 are the pricipal axes. Section properties can also be calculated for an axis parallel to either side, perpendicular to either side, or at a user defined angle relative to the L axis. The trapezoid geometry should be arranged so that the offset is positive. Refer to the figure for more details.
