You’re amazing! Thank you for these awesome videos! ❤

Why don't we convert Coordinates. NT for BA isnt the same as NT of BC and AO

If we have a negative velocity for one of the members ~BC for example, say its in the clockwise direction, do we still use omegaBC*k? Thanks

if our Wab is -3.017 rad/s for ex do we sub it in as k or J?
