I have two white 24t clutch gears, one marked as 2.5-5Ncm and another unmarked - how can I assembled them in a way to test which one "gives" first ) i.e. has torque before it slips - I was thinking to lock the axle on both and then driving them through a differential, but I am not sure how "fair" or symmetric a lego differential would be for driving them, and also noticed that they don't have a constant torque, but rather a shifting amount depending on the position, so some way to determine both the peak and average torque of them would be ideal, but I am not sure of as to design such as test, thus this question:
How can I test two clutch gears to determine their differences?
