in a dynamics problem the example in a book shows a circular rod rotating about a pin at the end. Now the author says that the
cg of the rod is at a point and he draws an acceleration vector from cg towards the pin and says that it is the normal acceleration and a perpendicular component called tangential acceleration. My question is why these two acceleration vectors should be drawn from cg why not
from any other point in the rod and the problem solved
