I cannot seem to be able to find which unit applies to the integral of torque over time. If you compress a bracket shaped load cell, you exercise torque on it, say 5 Nm. Now, say you do this for 5 seconds, by integrating it you get an area of 25 .. Nms? which would be... angular impulse? can I also represent this as watts or other units of power?
This shows a use case, where the load cell's angle is increased as the leg expands. We can determine the torque of the knee's angular movement. So, measuring this as a function of time, it only give you an angular impulse, but no way to determine power from this, is this correct?
