5. Calculate: The mechanical advantage of a lever is how much it multiplies your effort. If you can lift a 1200-N sheep with only 600 N of effort, the lever doubled your effort, so its

mechanical advantage is 2. (Notice you can just divide load by effort: 1200 + 600 = 2.)

Calculate the mechanical advantage of the lever with the strongman at each distance:

2 meters:

3 meters:
