The TX function returns the x-component of the net torque acting at marker i, as computed in the coordinate system of marker k. All force and constraint elements acting between markers i and j are included in the calculation of the torque, unless a force element is an action-only type force. To return the x-component of the action-only torques acting at marker i, you should omit specification of marker j or specify it as zero. Note that you can not specify marker k and omit marker j. In this case, you should specify marker j to be zero.
TX(i[,j][,k])
| i | An integer that specifies the identifier of the marker at which the magnitude of the net torque is to be calculated. |
| j | A second integer that specifies a marker identifier. All torques acting between the [i,j] pair are to be included in the calculation. Set j = 0 or do not specify it if you are interested in action-only torques. |
| k | An integer that specifies the identifier of a marker (coordinate system) in which the x-component of the torque is to be returned. k defaults to the global coordinate system when it is not specified. |
TX(32,44)
This function returns the x-component of the magnitude of the net torque between Markers 32 and 44.
