Hi there, I am currently trying to work out what force I will need to pull the curtain out and in (in the system shown in the attached illustration) so that I can calculate the torque required to turn the black cylinder component and therefore find out what motor I will need.
I am simply looking for a place to start or even a rough outline of how this can be calculated since at the moment I don't even know where to begin. It seems like there are forces all over the place in different dimensions and I am not sure how to simplify this for hand calculation.
If a hand calculation will be too difficult, is there anyway I could set up a simple experiment to calculate it?
Thanks for your time
