TX(I, J, K)

Description

The TX function computes the X-component of the resultant torque acting at marker I (obtained by vector summation), due to all applied torques and constraints that act between marker I and marker J, as resolved in the coordinate system of marker K. If the J marker is not specified, then TX computes the X-component of all the resultant torques at marker I.  The first argument, marker I must be specified.  The second and third arguments, markers J and K, are optional.      

Example

    comment          = "bush-frc"

    id               = "70000045"

    type             = "EXPRESSION"

    expr1            = "NULL"

    expr2            = "FX(30301010,30301011,30301011)"

    expr3            = "FY(30301010,30301011,30301011)"

    expr4            = "FZ(30301010,30301011,30301011)"

    expr5            = "NULL"

    expr6            = "TX(30301010,30301011,30301011)"

    expr7            = "TY(30301010,30301011,30301011)"

    expr8            = "TZ(30301010,30301011,30301011)"

Arguments

I

The marker at which the resultant torque is to be computed.

J

The second marker such that all torques between markers I and J are to be summed up at the marker I location.

K

The resultant torque 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.
