FY

The FY function computes the Y-component of the resultant translational force acting at marker I (obtained by vector summation), due to all applied forces and constraints that act between markers I and J, as resolved in the coordinate system of marker K.

Format

FY(I, J, K)

Description

If the J marker is not specified, then FY computes the Y-component of all the resultant forces at marker I. The first argument, marker I must be specified. The second and third arguments, markers J and K, are optional.

Arguments

I: The marker at which the resultant force is to be computed.
J: The second marker such that all forces between markers I and J are to be summed up at the marker I location.
K: The resultant force vector is resolved in the coordinate system of the K marker. This argument is optional. If omitted, it defaults to the ground coordinate system. To specify a K marker without specifying a J marker, set the J marker to zero.
