A man uses 65 N to lift a box off the ground with a lever. The effort arm is 60 cm. The resistance arm is 10 cm. What is the Ideal Mechanical Advantage?
billnyerocks said:I know that the IMA of a lever is Le divided by Lr, which is Lever effort divided by lever resistance, so when you divide 60 cm by 10 cm, you get 6 cm. But what is the 65 N for?
