Unformatted text preview: 4. (Bonus: 25 points) A 100-lb vertical force is applied to the end of a lever which is attached to a shaft at O . Determine (a) the moment of the 100-lb force about O ; (b) the magnitude of the horizontal force applied at A which creates the same moment about O ; and (c) the smallest force applied at A which creates the same moment about O . 5. (Bonus: 25 points) Determine the distance from point A to the line of action of the resultant force when (a) a=1m, (b) a=1.5m, (c) a=2.5m...
