Web• The fingers represent a position vector from to the line of action of • Curl the fingers in the direction that would rotate such that it would point in the direction points • The thumb is pointed into the figure and the moment is Clockwise. • Since we defined Counter Clockwise moments as positive, this moment is negative.????? WebHere's a simple one that will work with non-convex polygons (it'll even work with a self-intersecting polygon like a figure-eight, telling you whether it's mostly clockwise). Sum over the edges, (x 2 − x 1 ) (y 2 + y 1 ). If the …
