The TM function returns the magnitude of the net torque acting at marker i. All force and constraint elements between markers i and j are included in the calculation of torque, unless it is an action-only type. To return the torque magnitude of the action-only forces acting as marker i, you should omit specification of marker j, or specify it to be zero.
Format
TM(i[j])
Arguments
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. |
Examples
JOINT/1, REVOLUTE, I=32, J=44
MOTION/1, ROTATION, JOINT=1, FUNCTION=10*TIME
VARIABLE/31, FUNCTION=TM(32,44)
In this example a revolute joint and motion (through the joint) act between Marker 32 and 44. A new algebraically determined state variable VARIABLE/31 is defined to have the magnitude of the net torque between these two markers as its value.
