Levers! Wahoo!

  1. May 17, 2005 #1
    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?

    You need to show us an attempt to solve the problem yourself. What have you tried?

    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?
