Dotted lines run above and parallel with the bar and vertically from the above dotted line to the center of the weight, the point where the triangle meets the bar, and the finger. The distance from the center of the weight to the point of the triangle is labeled 2 meters. The distance from the point of the triangle to the finger is labeled 5 meters. For the lever shown, a = 5 m and b = 2 m. What is the mechanical advantage of the lever? ill give 14 points if youll be my boo if your a girl
