hmm it is indeed tricky to obtain same conditions for the belt.
maybe if i detached the belt completely and assumed that it is >90% efficient?
>You can put several resistances between the terminals and measure the voltage and the force at different speeds
how would I go about that with the different forces?
would it be a solution to attach a string to the pulley and different wights at the end of it and measure distance, time and the given force (gravity)?

and if i didnt do any of this, which curve would you go with?
do you think >>617591
is accurate enough?
