Hello,
I'm trying to setup a simple FEM static analysis of a bike dropout to figure out metal breaking point. Model is done and software seems to work. Though I could use some help with the physics. For an instance, what's the max. force a 12mm hub motor axle edge would put on a dropout face if the motor has a torque rating of 100 n.m-2 ?
I get that 100n.m-2 means a force of 100N perpendicular to the axle, applied at a distance of 1m. Now if I take this same force 5mm from the axle center, I get 1000/5*100 = 20 000N which seems just silly. What am I doing wrong ?
Thanks for your time,
