What if the normal force was acting 2m away from the centroid? Should I recalculate my acceleration in the x and y and alpha?

[@engineeringdeciphered]

It would get much more complicated. It would be tipping, so I would set N out to the outside edge, and recalculate everything. Alpha is no longer zero.

@@engineeringdeciphered Well thank you. I love translational rigid bodies they are way easier than general plane motion

Where did the sum of the moments of g numbers come from

[@fkj7161]

I think I see, it’s just the forces times their distance from G
